Question

angle efb is 108 find the size of angle x

Answer 1

TO FIND

the size of the angle

GIVEN

size of one angle= 108

SOLUTION

according to sum of complementry angle=180

here one angle is given =108

let the second angle be x.

so,

the angle is

x+108=180

x=180-108

x=72

ANSWER

the value of second angle x is 72

Answer 2

Given:

∠EFB = 108°

To Find:

The size of angle x

Solution:

As it is given that ∠EFB = 180°

Now, as we know vertically opposite angles are equal.

So, ∠HFG = ∠EFB [ they are vertically opposite]

And also ∠HFG = x°

This means that the size of angle x will be equal to the size of angle HFG which is again equal to angle EFB as they are vertically opposite angles so,

∠x = ∠HFG = 108°

Therefore, the size of angle x will be 108°.
