The angles in a triangle have measures of 90°, 65°, and (x – 10)°. What is the value of x?
A 15
B 25
C 35
D 45
Two angles are supplementary. One angle has a measure of x° and the other angle has a measure of 30°. Which equation could be used to determine the value of x?
A x + 30 = 180
B x + 30 = 90
C x = 30 – 90
D x = 30 – 180
The three angles in a triangle have measures of 35°, 120°, and x°. Which equation below could be used to determine the value of x?
A 35 + 120 + x = 360
B 35 + 120 + x = 180
C 35 + 120 = x
D 35 + 120 + x = 90
Two complementary angles have measures of 15° and (x+5)°. What is the value of x?
A 70
B 75
C 80
D 160
The three angles in a triangle have measures of 55°, 75°, and (2x)°. What is the value of x?
A 130
B 100
C 50
D 25
Two supplementary angles have measures of (2x)° and (x – 30)°. Which equation could be used to determine the value of x?
(2x) + (x – 30) = 90
(2x) = (x – 30)
(2x) + (x – 30) = 360
(2x) + (x – 30) = 180
The three angles in a triangle have measures of (x)°, (2x)°, and (3x)°. What is the measure of the greatest angle?
30°
60°
90°
180°
Two supplementary angles have measurements of (3x)° and (10x – 15)°. What are the measures of the two angles?
45° and 135°
25° and 65°
15° and 165°
30° and 60°
The three angles in a triangle have measures of (3x+2)°, 40°, and 120°. What is the value of x?

Two complementary angles have measures of (x+7)° and (3x)°. Which equation could be used to determine the value of x?
(x+7) + (3x) = 180
(x+7) + (3x) = 90
(x+7) = (3x)
(3x) – 90 = (x+7)
