Answer:
The slope is 0.5 or (1/2)
Step-by-step explanation:
Find the rise over run.
from -3 to -1 and 2 to 3 rises 1 runs 2 so then you divide 1/2 and get 0.5.
66 is the answer
76+ 38= 114
114+ 66 = 180
Answer:
a = 85° , b = 30° , c = 65°
Step-by-step explanation:
∠ a and 85° are alternate angles and are congruent , so
a = 85°
∠ c and 65° are alternate angles and are congruent , so
c = 65°
a, b and c lie on a straight line and sum to 180° , that is
a + b + c = 180°
85° + b + 65° = 180°
150° + b = 180° ( subtract 150° from both sides )
b = 30°
