The answer is .... Tan C = √3 By trigonometric table, tan = √3, then C = 60° By angle sum property, ∠a + ∠b + ∠c = 180° 90° + ∠b + 60° = 180° ; 150° + ∠b = 180° ∠b = 180° - 150° ; ∠b = 30° By trigonometric table, Sin B = Sin (30°) = ½ Cos B = Cos (30°) = √3/2 Sin C = Sin (60°) = √3/2 Cos C = Cos (60°) = ½ Sin B x Cos C = ½ x ½ = ¼ Cos B x Sin C = √3/2 x √3/2 = ¾ From the equation, Sin B Cos C + Cos B Sin C = ¼ + ¾ = 4/4 = 1. So the answer to this equation is 1.
I have a doubt... Can we also solve this equation like this ↓? From equation, Sin B Cos C + Cos B Sin C By rearranging, Sin (B+C) + Cos (B+C) = Sin (30º + 60º) + Cos (30º + 60º) = Sin (90º) + Cos (90º) By trigonometric table, Sin (90º) = 1 Cos (90º) = 0 From the factorization, Sin (90º) + Cos (90º) = 1 + 0 = 1
if it helps please like... for sin cos and tan theta if someone is using adjascent opposite and hypotenuse an easy way to remember this is Old Henry for O/H (opposite by hypotenuse for sin theta), And His for cos theta Old aunt for tan theta so the sentence formed will be Old Henry And His Old Aunt
I think the answer for the homework question is 1, as tan 60 is √3/1. The hypotenuse will be 2 when calculated by Pythagoras theorem. Therefore, sin B=1/2 and B is 30. cos C=1/2 and sinBcosC is 1/4. cosB is √3/2 and sinC is √3/2 and cosBsinC is √3/2 * √3/2 = √9/4 = 3/4. When they are added 1/4+3/4= 4/4=1, so the answer for the question must be 1..
It's even more easier as we learned in school to call those formulas with sides, adjacent, etc... but here with calling it as perpendicular and hypotenuse like p/h, b/h, p/b makes it more easier than that type

Q). *In a right angle triangle, if A = 90° and tanC = √3 then find sinB cosC + cosB sin C*
Sol:
*Method1:*
tanC = √3 = tan60°
⇒C = 60°
We know that A + B + C = 180°
⇒90° + B + 60° = 180°
⇒B = 30°
∴ *sinB cosC + cosB sinC*
= sin30° cos60° + cos30° sin60°
= (1/2)(1/2) + (√3/2)(√3/2)
= 1/4 + 3/4
*= 1*
*Method2:*
*sinB cosC + cosB sinC*
= sin(B+C)
= sin(180°-A)
= sinA
= sin90°
*= 1*

Good luck👍

Not Gonna Lie but MANOCHA ACADEMY IS BETTER THAN BYJU'S
Thanks a lot :)
true af
Really
Yes
Absolutely right.
The answer is ....
Tan C = √3
By trigonometric table,
tan = √3, then C = 60°
By angle sum property,
∠a + ∠b + ∠c = 180°
90° + ∠b + 60° = 180° ; 150° + ∠b = 180°
∠b = 180° - 150° ; ∠b = 30°
By trigonometric table,
Sin B = Sin (30°) = ½
Cos B = Cos (30°) = √3/2
Sin C = Sin (60°) = √3/2
Cos C = Cos (60°) = ½
Sin B x Cos C = ½ x ½ = ¼
Cos B x Sin C = √3/2 x √3/2 = ¾
From the equation,
Sin B Cos C + Cos B Sin C = ¼ + ¾ = 4/4 = 1.
So the answer to this equation is 1.
I have a doubt...
Can we also solve this equation like this ↓?
From equation,
Sin B Cos C + Cos B Sin C
By rearranging,
Sin (B+C) + Cos (B+C) = Sin (30º + 60º) + Cos (30º + 60º)
= Sin (90º) + Cos (90º)
By trigonometric table,
Sin (90º) = 1
Cos (90º) = 0
From the factorization,
Sin (90º) + Cos (90º) = 1 + 0 = 1
@@user-sj6hy8ze8c
sinB cosC + cosB sinC
= sin(B+C) + cos(B+C)
*This is wrong.*
*Formula:* sin(A+B) = sinA cosB + cosB sinA
∴ *sinB cosC + cosB sinC*
= sin(B+C) *This is correct.*
= sin(180°-A)
= sinA
= sin90°

I think the answer for the homework question is 1, as tan 60 is √3/1. The hypotenuse will be 2 when calculated by Pythagoras theorem. Therefore, sin B=1/2 and B is 30. cos C=1/2 and sinBcosC is 1/4. cosB is √3/2 and sinC is √3/2 and cosBsinC is √3/2 * √3/2 = √9/4 = 3/4. When they are added 1/4+3/4= 4/4=1, so the answer for the question must be 1..
Sir, the answer is 1 , here are the steps, angle b=30 degree, angle c=60 degree, 1/2×1/2+√3/2×√3/2=1/4+3/4, =4/4 that's 1
Perfect answer
Super! Right answer :)
Who u find angle b pls tell me
Angle b=30
Q
A=90°, B=30⁰, C=60⁰
= SinB (1/2) x cosC (1/2) + cosB (√3/2) x sinC (√3/2)
= 1/4+3/4
= 4/4
= 1
Answer 1
Yes😄

For guys who don't understand
I explained you have seen protractor which is shaped like D
We use D to draw angle we draw 90°angle which is called right angle a right angle have 3 side hypotenuse adjacent and opposite the diagnol line is hypotenuse right to it is opposite and left is adjacent
When you take length of adjacent and make it square the make square with opposite side which number is given is given then you got square of hypotenuse in math it is called Pythagoras theorem a²+b²=c²
Adjacent is 3cm opposite is 4cm
Then according to Pythagoras theorem 3 square is 9 and 4 square is 16 and a²+b²=c²
9+16=25 and √25=5 length of hypotenuse is 5 cm
