Question

Ques 20
Pls ans its my exam

Answer 1

Use tye Pythagorean Theorem

H^2 = P^2+B^2

Answer 2

mark brainliest plzzzz....

Angle BAD = Angle ADC

But they're co interior angles. Thus, AB || CD.

Also, AX || BC, this implies, ABCX is a parallelogram.

Therefore,

AB = CX = 5 cm (opposite sides of parallelogram are equal)

Also, AX = BC = 5 cm

Now, DX = DC-CX = 8-5 = 3 cm

In ∆ADX, using Pythagorean theorem, we get,

AD = 4 cm

Now, in parallelogram ABCX,

Base = 5 cm

Height = 4 cm.

Therefore,

ar (ABCX) = Base × Height

= 20 cm²
