Answer
7. 30
8. 54
Step-by-step explanation:
For 7 do 2x+3x=90 because it is a right angle
then solve for x and get 15
to get the angle you are looking for multiply 2 by 15
and get the answer 30
For 8 to find the value of x you would need to...
add (4x+6) + (11x-6)= 180 because 180 is a straight angle.
Then simply solve for x and get 15x=180 which equals 12
The to get the angle you plug it in to (4x+6) and get the answer 54
