Answer:
x = 3
Step-by-step explanation:
given
4(x - 8) + 10 = - 10 ← subtract 10 from both sides
4(x - 8) = - 20 ← divide both sides by 4
x - 8 = - 5 ← add 8 to both sides
x = 3

Answer:
∠ABC= 40° ∠CBD=60° ∠EBD=80°
Step-by-step explanation:
Step 1: 2x+3x+4x=180
A straight line is 180 degree's, and to get the value of the different angles, you have to add the three angle measures.
Step 2: 9x=180
Combine like terms
Step 3: x=20
Divide/ Isolate the variable
Step 4: 2(20)=40 3(20)=60 4(20)=80
