Question

Evaluate Sin(60°+90°)​

Answer 1

Step-by-step explanation:

1. In the right angle triangle, Sin 60 value is the ratio of the length of the perpendicular side to the length of the hypotenuse.

2. Based on the above diagram,

3. The ratio of Sin 60 = Perpendicular/ Hypotenuse.

4. The method to calculate the Sin 60 degree exact value is to divide v3 by v4 or v3/v4. 5. With this, we got.

Answer 2

Answer:

We know that sin 60 and sin 90 value , so put them into equation..

sin(√ 3/2 + 1)

now cross multiply.

√3/2+2

$\sqrt{3} \div 2 + 1 \\ \sqrt{3} + 2 \div 2 \\ 2 \sqrt{3 } \div 2$
