Maths question for class 7​

Answer 1

Answer:

Hey there!

Step-by-step explanation:

First let's know some terms!

1. Linear Pairs : All the angles on a straight line if added up gives 180°.

2. Alternate Angles : If you see figures forming Z or mirror image of Z then those are alternate angles.

3. Angle Sum Property : Sum of all angles of triangle is 180°.

Now for your question,

Angle EBH + BHI + IHF = 180° ...(linear pairs)

So, 45° + H + 64 = 180°

Angle H = 71°

Also H = C + 32° ...(Alternate Angles)

71° = C + 32°

Angle C = 39°

And 64° + d + c = 180° ...(angle sum property)

So d = 77°

Hence your answer!
