The total measure of all the angles in a triangle is 180°.
Since there is already a 90° angle, the other 2 angles must also add up to 90°.
The only answer that fits is x = 9.
Check:
9x7 = 63°
3x9 = 27°
Add up = 90°

You must first simplify the radicals by taking out any perfect squares.
√8 + 3√2 + √32 =
√4 * √2 + 3√2 + √16 * √2 =
2√2 + 3√2 + 4√2 =
9√2
Answer:
80
Step-by-step explanation:
The Two-Tangent Theorem states that if two tangent segments are drawn to one circle from the same external point, then they are congruent
13+13+9+9+12+12+6+6= 80
