Anyone know the answer to these questions ?

see explanation

Step-by-step explanation:

Using the tangent ratio in the right triangle and tan45° = 1

tan45° = = = 1 ( multiply both sides by 7 )

x = 7

---------------------------------------------

(8)

Using the cosine ratio and cos45° =

cos45° = = = ( cross- multiply )

y = 7

answer: (c) m∠qpo + (2x + 16)° = 180°

step-by-step explanation:

the opposite angles of a quadrilateral are supplementary.

so, ∠o + ∠q = 180°   and   ∠p + ∠r = 180°

since ∠r = 2x + 16°, we can use substitution as follows:

∠p + ∠r = 180°

∠p + (2x + 16)° = 180°

$3,200 x 7.25% = $3,200 x .0725 = $232 interest monthly

$232 monthly x 12 annual = $2, 784
