Step-by-step explanation:
Answer:66
Step-by-step explanation:
The first thing we should know is that a kite has two pairs of adjacent congruent sides, so to find the value of x we are going to set the equations equal to each other. The value of x is 4. After, plugging the value of x into the equations the measure of both angles is 33. Angle TUV is made up of angles TUW, and VUW because of the measure of angle TUV is 66.
10x-7=5x+13
5x=20
x=4
10(4)-7=33
5(4)+13=33
