Question

Angle XYZ = 2X ° and angle PQR = (8X -20)° if angle XYZ and angle PQR or supplementary find the measure of each angle angle XYZ = ?

Answer 1

angle XYZ = 40°

Explanation:

given,

angle XYZ = 2x°

angle PQR = (8x-20)°

now,

2x+8x-20° = 180°{being supplementary angle}

or, 10x - 20° = 180°

or, 10x = 180°+20°

or, x = 200°/10

or, x = 20°

again,

angle XYZ = 2x°

= 2× 20°

= 40°
