Question

In parallelogram XYZW, YZ = 8 cm. If its area is 120 cm?, find altitude XM on base YZ.

DRAW THE ANGEL.​

Answer 1

Step-by-step explanation:

Correct option is C)

Since, XY=YZ

i. e., ΔXYZ is an isosceles triangle

Also, we know that the angles opposite to equal sides of an isosceles triangle are equal

Thus, if XY=YZ, then ∠Z=∠X.

Answer 2

Answer:

Altitude is 15 cm and it forms an isosceles triangle.

Step-by-step explanation:

Area of parallelogram,

A=b×h

120=8×h

h=120/8

h=15

The altitude is 15 cm.

Since it forms an isosceles triangle and sum of its angles is 180°, the angle at the top of the triangle will be less than 60° and the 2 angles at the base will be greater than 60° but less than 90°.
