M∠cbd=4x+52∘

m∠abc=8x−10∘\qquad m \angle abc = 8x - 10^\circm∠abc=8x−10∘

find m∠cbdm\angle cbdm∠cbd:

 The value of ∠CBD is 98°.

Step-by-step explanation:

Since we have given that

m∠CBD=4x+52∘

and

m∠ABC=8x−10∘

As we know that they are linear pairs.

As we know that a linear pair is a pair of adjacent angles when two lines get intersected by a line say BC.

So, Sum of linear pair is supplementary.

So, m∠CBD = 4x+52=4(11.5)+52=98°

Hence, the value of ∠CBD is 98°.
