Answer:
True, because they are under 180 degrees
"Supplementary angles are two angles with a sum of 18 0 ∘ 180 ^\circ 180∘ . A common case is when they lie on the same side of a straight line."
3 times (2x + 5) is 6x + 15.
6x + 15 = 9 + 3x.
Group by like terms. 6 = -3x
Divide to get x by itself. 6/-3 = -2
Thus -2 = x
Answer:
60 for both
Step-by-step explanation:
Since these angles are parallel, they are equal to each other :
6x = 5x + 10
Subtracting 5x from both sides gives us :
x = 10
Substituting this value back into both angles gives us
6x = 60
5x+10 = 60
Answer:
A = 169cm²
Step-by-step explanation:
18 (m + 4/9) - 16 = 118 Get rid of the parentheses by multiplying 18 * M + 4/9
18M + 8 - 16 = 118 Subtract 8 - 16
18M - 8 = 118 Add 8 to both sides
18M = 118 + 8 Add 118 + 8
18M = 126 Divide 126/18
M = 7
