Sin60 = X/10√ ̅3

X=15 cm

And in triangle: (10√ ̅3)^2 = 15^2 + y^2

Y=√ ̅75= 5√ ̅3

The answer is D

What value of θ makes cosθ = sin70° a true statement?<br> A) 20° <br> B) 40° <br> C) 70° <br> D) 90°

Delvig [45]

Answer:

A) 20°

Step-by-step explanation:

Sine and cosine are co-function complements which means that value of sine of an angle is equal to the value of cosine of the complementary angles.

This can be represented by:

$\sin\theta=\cos(90\°-\theta)$

$\cos\theta=\sin(90\°-\theta)$

Given statement:

$cos\theta=\sin70\°$

Applying co-function complements

$\cos\theta=\sin(90\°-\theta)$

Since, we can represent 70° = 90°-20°

So

$\cos20\°=\sin(90\°-20\°)$

Thus, $\theta=20\°$ makes the statement true.
