Answer:

39 degrees

Step-by-step explanation:

If EFG is a right angle, then it is 90 degrees. EFG is made up of angles x+12 degrees and x, so you can write as an equation: x + 12 + x = 90

solve from there:

x + 12 + x = 90

2x + 12 = 90

2x = 90 - 12

2x = 78

x = 78 / 2

x = 39

M angle D=? What is the degree of the angle?

bekas [8.4K]

Answer:

Step-by-step explanation:

In ACB and ECD

AC =~ CE [ Given ]

BC =~ CD [ Given ]

<ACD =~ <ECD [ Vertical angles ]

Hence, ∆ ACB =~ ECD by SAS congruency of triangles.

Then, <B = <D

In ∆ABC , sum of all three angles must be 180°

<A + <B + <C = 180°

plug the values

$30 + < d \: + 70 = 180$

Add the numbers

$100 + < d = 180$

Move constant to R.H.S and change it's sign

$< d = 180 - 110$

Subtract the numbers

$< d = 80$ °

Hope this helps..

Best regards!!
