Answer:
the value of x = 10°
Step-by-step explanation:
here's the solution :-
we know that, the measure of exterior angle of the triangle is equal to the sum of opposite two interior angles.
so,
=》5x - 7 + 6x + 14 = 14x - 23
=》11x + 7 = 14x - 23
=》7 + 23 = 14x - 11x
=》3x = 30
=》x = 30 ÷ 3
=》x = 10°
