Question

please answer this question fully. if uou dont know pls dont answer. this questions is based on grade 9 quadrilaterals ​

Answer 1

Answer 1:

By midpoint theorem,

$AB = \frac{1}{2} QR = \frac{1}{2} \times 25 = 12.5cm$

Answer 2:

By midpoint theorem,

DE || BC

So,

y = 70 °. [corresponding angles]

z = 60°. [corresponding angles]

therefore,

x = 180 - (70 + 60)

x = 180 - 130 = 50°
