Solve for n.
2n + 6 = 46
n = 20
Two vertical angles are given. One angle measures 84 degrees and the other measures 3x degrees. Find the value of x.
x = 28
Solve for n.
83 = -3n - 25
n = -36
Two complementary angles are given. One angle measures 46 degrees. The other angle measures 4x degrees. Find the value of x.
x = 11
Solve for n.
5n+35 = 60
n = 5
The angle measures in a triangle are 29 degrees, 88 degrees, and x degrees. What is the measure of the missing angle?
63 degrees
Solve for n.
(n/3) - 17 = 4
n = 63
Determine whether the statement is always, sometimes, or never true and explain your reasoning:
Two obtuse angles are supplementary.
Never. Obtuse angles are greater than 90 degrees so the sum of two obtuse angles must greater than, not equal to 180 degrees
Solve for r.
-0.6(r + 0.2) = 18
r = -3.2
The angle measures in a triangle are 3x - 11, 6x - 10, and x. Find the value of x, then find the angle measures in degrees and then state what type of triangle this is based on angle measures.
x = 20.1
Angle measures: 49.3, 20.1, 110.6.
Obtuse
