let the exterior angle be x
x=60°+80°(being one exterior angle is equal to two interior angle)
x°=140°
Answer:3/2
Step-by-step explanation:
The measure of a straight line is 180
125+30=155
180-155=25
x = 25
Perpendicular bisectors are segment that passes through the mid point of a triangle, while altitude is the perpendicular distance from the base to the opposite vertex.
1/4(8m - 4n) + 1/3(6m + 3n)=
Distribute the fractions through the parentheses
2m - n + 2m + n =
Combine like terms
2m + 2m - n + n = 4m
The answer is 4m
