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°

$\cos20\°=\sin(90\°-20\°)$

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

Factor the polynomial completely x^2-x-20

Strike441 [17]

Answer:

(x − 5) (x + 4)

Step-by-step explanation:

x² − x − 20

Factor using AC method:

1 × -20 = -20

Factors of -20 that add up to -1: -5 and 4

Divide by 1 and reduce: -5/1 and 4/1

(x − 5) (x + 4)
