Question

can any one help me please

Answer 1

$\fbox\blue{THEORUM~-~Exterior~angle~is~equal~to~sum~of~interior~opp.~angles}$

$\large{\sf{2x + \frac{3x}{4} = 110}}$

$\large{\sf{ \frac{8x + 3x}{4} = 110}}$

$\large{\sf{ \frac{11x}{4} = 110}}$

$\large{\sf{x = 110 \times \frac{4}{11} }}$

$\large{\sf{x~=~40}}$

$\pink{\sf\bold{Value~of~x~=~40°}}$

2 angles are 80° & 30°
