Answer:
Step-by-step explanation:
Answer:
Solved using the <u>Exterior angle theorem</u>.
2x-5+x-17 = 128
3x-22 = 128
3x = 150
x = 50
Radius is 15 cm
Circumference = 2 pi r
C = 2 x 3.14 x 15cm
C = 94.2 cm
94.2 cm x 4 (revolutions) = 376.8 = D
Answer:
20meter per second is tw correct answer
ANSWER
111.3 square units.
EXPLANATION
The formula for calculating the area of a triangle is.

Let us the side of the triangle with side 12 units to be the base of the triangle.
Then the height of the triangle can be determined from the diagram using trigonometry.



We now plug in the values in to the formula to obtain,
