Answer:
The diameter of the circle is 40 units
Step-by-step explanation:
Answer: The angle's sine is 0.6. Divide the measurement of the side adjacent to the angle with the measurement of the hypotenuse to find the cosine of the angle. Divide the measurement of the opposite side with the measurement of the adjacent side to find the tangent of the angle.

QUESTION 4
RH is the hypotenuse of the right triangle formed by the triangle with side lengths, RH,12, and 20.
Using the Pythagoras Theorem, we obtain;
QUESTION 5
The given figure is an isosceles trapezium.
The base angles of an isosceles trapezium are equal.
Therefore
QUESTION 6
The measure of angle Y and Z are supplementary angles.
The two angles form a pair of co-interior angles of the trapezium.
This implies that;
