<h2>(x + 4) (x + 4)</h2>
Step-by-step explanation:
= x² + 8x + 16
= x² + 4x + 4x + 16
= x (x + 4) + 4 (x + 4)
= (x + 4) (x + 4)

It’s 20f-30g I just took that question on a test
A theorem requires a proof.
<h2>○=> <u>Correct option</u> :</h2>
![\color{plum}\tt\bold{(D) \: 70}](https://tex.z-dn.net/?f=%5Ccolor%7Bplum%7D%5Ctt%5Cbold%7B%28D%29%20%20%5C%3A%2070%7D)
<h3>○=> <u>Steps to derive correct option</u> :</h3>
Angle 1 and angle 3 are vertically opposite angles.
We know that :
▪︎ Vertically opposite angles are always equal.
Which means :
Angle 1 = Angle 3
Thus, the measure of angle 3 = 70°
▪︎Therefore, the correct option is (D) 70
