Answer:
a= 180-60-55=65
we know that the angle of a flat(?) ground would be 180, so we can take away the 60 and 55 to find a.
b=180-90-65=25
the sum of interior angle of a triangle would be 180, now we know what a is, also the right angle is 90, now we can take away the 90 and 65 to find b.
c=25
c is 25, because two angles on both sides of a X is the same
Answer:
c = -16
Step-by-step explanation:
2c = -32
c = -16
Answer:
Step-by-step explanation:
angles in triangle = 180
1. 180 - (70+45) = x = 65
2. x = 35
180 - 110 = 70
70/2 = 35 (isosceles triangle)
3. x = 113, y = 67
180 - (62 + 51) = y = 67
Angles on a line = 180
180 - 67 = x = 113
4. x = 60, y = 50
x = 180 - 120 = 60
y = 180 - (60 + 70) = 50
