Answer:
b. 0.86, 0.87
Step-by-step explanation:
a. Find attached solution to a
The answer is 80 degrees. As you can see, the triangle is an isosceles triangle and both sides of the triangle equal 14. If both of the sides are congruent then the opposite angles are also congruent as well. Which means the 50 degrees in the left angle is congruent to the right angle, 50. Since triangles add up to 180 degrees, the answer for x would be 80.
