6x2 + 2x2 = 16
Remember that it has 4 sides. That’s the trick in the ?

Answer:
(5,7 6,2 4,8 1,3) and (7,1 5,3 4,8 6,2)
So this is trig, and when it comes to right (90°) triangles, it's imperative that you know:
SOH-CAH-TOA
Sine (x) = Opposite/Hypotenuse
Cosine (x) = Adjacent/Hypotenuse
Tangent (x) = Opposite/Adjacent
*hypotenuse is always the largest side, and the one opposite the 90° angle in right triangles
therefore we'll use SOH, because the opposite of x (O) and the hypotenuse (H) are given:
Sine (x) = Opposite/Hypotenuse
Sine (x) = 32/58 = 16/29 = 0.552
Sine (x) = 0.552
now we use something called arc-sine, or

it's basically a fancy function of most advanced calculators, so we'll plug it in as:

x = 33.49° --> answer B) is correct
Answer:
3x + 21 is your answer
Step-by-step explanation:
3(x+7)
3 × x = 3x
3 × 7 = 21
3x = 21
