Question

solve this question number 7

Answer 1

(2x-8)°+(3x-7)°=180°
Since sum of two interior angles = 180°(PROPERTY)
2x-8+3x-7=180
5x-15=180
5x=180+15
5x=195
X=195/5
X=39
:.First angle=2×39-8=78-8=70
& Second angle=3×39-7=117-7=110

Answer 2

$(2x - 8) + (3x - 7) = 180 \\ 2x - 8 + 3x - 7 = 180 \\ 5x - 15 = 180 \\ 5x = 180 + 15 \\ x = \frac{195}{5} \\ x = 39$
now substitute the value of X.
you will get your answer.
