Secant and tangent theorem: Square of measure of tangent is equal to the product of length of whole secant and length of exterior secant segment, i.e.

$\text{ tangent }^2=\text{whole secant}\cdot \text{exterior secant}$ .

The whole secant wuth exterior secant 4 cm is 4+x cm. Tangent is 7 cm. Using previous theorem, you can get that

$7^2=(4+x)\cdot 4$ .

Solve this equation:

$49=16+4x,\\ 4x=49-16,\\ 4x=33,\\ x=8.25\approx 8.3$ cm.

Answer: x=8.3 cm.

For what value of x is sin(x) = cos(32°), where 0°< x < 90°?

sergiy2304 [10]

Answer:

Step-by-step explanation:

Use the cofunction identies that states that

$\sin(90 - x) = \cos(x)$

$\sin((90 - x)) = \cos(32)$

$\sin(90 - 32) = \cos(32)$

$\sin(58) = \cos(32)$

B is the answer.
