Answer:

I HOPE THIS WILL HELP YOU :)

Step-by-step explanation:

115°=17x-4

adding 4 on both sides

115°+4=17x-4+4

119°=17x

dividing 17 on both sides

119°/17=17x/17

x=7

now we find the measure of angle

17(7)-4

=119-4

=115° same as angle R

Answer:

x = 7

115°

Step-by-step explanation:

Opposite angles in a parallelogram are equal.

17x - 4 = 115

Add 4 on both sides.

17x = 115 + 4

17x = 119

Divide 17 on both sides.

x = 119/17

x = 7

Plug x as 7 in angle T.

17(7) - 4

119 - 4

= 115
