Question

How would I do this? What would it be?

Answer 1

Explanation:

You can solve this by substitution method

Since AE is bisector

Angle BAE = angle. EAC

SINCE angle BAE=x+30

EAC= x+30

So, 3x-10= x+30

2x. = 40

x. = 40/2 = 20°

Thank you

Answer 2

50

Explanation:

Since AE is the bisector of angle BAC,so angle BAE and Angle CAE is equal. Here Angle CAE and Angle EAC is same.

therefore,

m(Angle BAE)=m(Angle EAC)

`x + 30 = 3x - 10`

or, 2x=40

or, x=20

Hence,

m(Angle EAC)=

`3x - 10`

=

`(3 * 20) - 10 = 60 - 10 = 50`
