Answer:
x=20
Step-by-step explanation:
Hello There!
Remember the exterior angle of a triangle rule:
An exterior angle of a triangle is equal to the sum of the opposite interior angles
Knowing this, we can create an equation to solve for x
exterior angle (100) = sum of opposite interior angles (3x+2x)
100 = 2x+3x
now we solve for x
step 1 combine like terms
2x+3x=5x
now we have 100=5x
step 2 divide each side by 5
5x/5=x
100/5=20
we're left with x = 20
Answer:
1 . -2 and 7. 2.-6 and 3 i think
Step-by-step explanation:
Answer:
30 - (20% × 30) =
30 - 20% × 30 =
(1 - 20%) × 30 =
(100% - 20%) × 30 =
80% × 30 =
80 ÷ 100 × 30 =
80 × 30 ÷ 100 =
2,400 ÷ 100 =
24
