A triangle measures to 180 degrees. So you would do 74 + 52 to get 126. Then you would do 180 - 126 to get 54.
Answer:
21.21
Step-by-step explanation:
length of arc= 135°÷360×2×π×r
take π=22/7
radius=18/2=9
135°÷360×2×22/7×9
using calculator= 21.21
Answer:
152°
Step-by-step explanation:
Supplementary angles are two angles that sum to 180°
Complementary angles are two angles that sum to 90°
Let x° = the angle
⇒ Supplement of the angle = 180° - x°
⇒ Complement of the angle = 90° - x°
The difference between the supplement of an angle and twice its complement is 28°:
⇒ (180 - x)° - 2(90 - x)° = 28°
⇒ 180 °- x° - 180° + 2x° = 28°
⇒ x = 28°
Therefore, the measure of the supplement of 28° is:
180° - 28° = 152°
