Answer:
x=8/21
Step-by-step explanation:
(3/4)/(2/7) = 1/x
(3/4)x = (2/7)
x = (2/7) / (3/4)
x = (2/7) * (4/3)
x = 8/21
The slope is 2, as for every 20 the graph rises, the line goes over 10, and the formula for slope is rise over run.
In first question Use trigonometry for finding angles
Similarly in second question use trigonometry to find value of x
In third question use formula 2πr to find circumference and radius is given to you in this question.
