Anyone me. ill give you brainliest and a lot of points.

First one is 135°

(measure of angle TUV = measure of angle DEF

 135°                               = measure of angle DEF)

Second one is 75°

(50° + x = 125° (Since one angle's measure is given and total measure is given)

x = 125° - 50°

x = 75°)

the correct answer is semicircle

step-by-step explanation:

the answer is semicircle because the shorter arc joining two points on the circumference of a circle is known as the minor arc, the larger arc is called the major arc, and a semicircle is a half circle, formed by cutting a whole circle along a diameter line.
