Answer:
5. x = 18°
6. 5x = 50°, 4x= 40°
Step-by-step explanation:
5. Both the angles shown above add up to 180, due to them being supplementary, so you get the following equation:
6x + 4x = 180
which simplifies to
10x = 180
meaning x is equal to 18.
6. The angle measures of 5x and 4x add up to 90 because they are complementary angles, giving us the equation below:
5x + 4x = 90
simplifying to
9x = 90,
and resulting in
x = 10
So 5x is equal to 50 and 4x is equal to 40.
