Answer:
x = 7
115°
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
Plug x as 7 in angle T.
17(7) - 4
119 - 4
= 115
I HOPE THIS WILL HELP YOU :)
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
