The 3 inside angles of a triangle need to equal 180 degrees.
Since you are given 2 angles, subtract both of those from 180 to find X.
X = 180 - 70 - 30 = 80 degrees.
X = 80
N the xy-plane above<span>, </span>O is the center<span> of the cirlce. In the </span>xy-plane above<span>, </span>O is the center<span> of the cirlce, and the </span>measure<span> of angle AOB is pie/a radians</span>
Answer:
96 ft²
Step-by-step explanation:
in a cube all sides are congruent so you take one measurement and multiply it by the number of sides, so you do 16 × 6 equals 96.
