Two supplementary angles when added together need to equal 180 degrees.
Let the first angle = X
The second angle would then be X - 152
Add them together to equal 180:
X + X - 152 = 180
Simplify:
2X -152 = 180
Add 152 to each side:
2X = 332
Divide both sides by 2:
X = 332 / 2
X = 166
The first angle = X = 166 degrees.
The second angle = X - 152 = 166 - 152 = 14 degrees.
The angles are 166 and 14
Answer:
6
Step-by-step explanation:
(x + 9) * (x - 2) = 60
x^2 - 2x + 9x - 18 = 60
x^2 + 7x - 18 = 60
x^2 + 7x = 78
FACTORING:
x(x + 7) = 78
x = 6
Answer:
upper bound = 112.5
lower bound = 111.5
Step-by-step explanation:
x = 360 - 59 - 108 - 81
x = 112°
upper bound = 112.5 < 113
lower bound = 111.5 < 112
so
L.B. U.B.
111.5 < 112 < 112.5
Answer: 6 Kilometers
