Answer is A) AC= 20 and angle A=37°
Dilated by factor of 4 means enlarged by 4 ( multiply by 4)

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.
