Answer:
x = 6
Explanation:
The Answer for the first figure:
m<5 and m<7 are equal, since they are corresponding angles. So, that means;
m<5 = m<7
12x + 4 = 10x + 16
12x - 10x = 16 - 4
2x = 12
x = 6 (when both divided by 2)
x= 6
You will subtract 10x from 12x and get 2x
Subtract 4 from 16 to get 12
You will then divide both sides by 2
=
The second one is hard to read but since ∠3 is 54° you should just start from there
