Solving Triangle Sum
27 + 82 + ? = 180
Solve....
Missing Angle = 71 degrees

Solving Exterior Angle
Equation
63 + 86 = x
X = 149

Isosceles Triangle
Legs are equal
Base Angles are equal
Vertex angle + 2 bases = 180
21
Find the missing angle
Angle Z has to be equal to x becuase it is a base angle
x + x + 84 = 180
Solve for x
X = 48
22
Find x
Labeled as sides (NOT angles so not 180)
2x - 9 = x + 5
Solve...
x = 14

Equilateral Triangle
Equal Sides
Also Equal Angles
Since angles are congruent, each angle is 60 degrees
29
Equilateral Sides
All sides must be = to 10
x = 10
y + 3 = 10, so y = 7
30
Equilateral angles
Start with x, which is 60
Then, use 60 to get to the other triangle... <ABC = 60, which makes <CBD = 120
120 + 35 + y = 180
y = 25
