its B. 50°
Triangle Have 180°
- 180 - 90 = 90
- 90 × 2 = 180
Half of triangle Have 90°
Answer:
D. 314 yds
Step-by-step explanation:
Given:
Diameter = 100 yds
Required;
Circumference of the circle
Solution:
Circumference of circle = πd
Plug in the value
Circumference = π × 100
= 314 yds (nearest whole number)

</span><span>
solve this:
(5x^7 y^2)(-4x^4 y^5)
= -20 x^(7 + 4) y^(2 + 5)
= -20 x^11 y^7

Answer:option A is the correct answer.
Step-by-step explanation:
The given triangle UVW is a right angle triangle. This is because one of its angles is 90 degrees. The sum of the two other angles is 180. To determine Cos U, we will apply trigonometric ratio.
Cos U = adjacent side/ hypotenuse.
Looking at the triangle with C as the reference angle,
Adjacent side = 12
Hypotenuse( always the longest side of the triangle) = 13
Therefore,
Cos U = 12/13
