Question

Questuon number one:

find m <CBE
​

Answer 1

25°

Explanation:

Vertically opposite angles are congruent.

m∠ABD = m∠CBE

3x + 10 = 2x + 15

Subtract 10 from both sides {Subtraction property of equality}

3x = 2x + 15 - 10

3x = 2x + 5

Subtract 2x from both sides

3x - 2x = 5

`\sf \boxed{x = 5}`

m∠CBE = 2x + 15

= 2*5 + 15

= 10 + 15

= 25°
