QUESTION 1 a

We were given that, line PQ is a tangent to the circle.


This tangent will meet the radius or diameter at an angle of
[tex]90 \degree[/tex]


This implies that,
[tex] < \: RQP = 90 \degree[/tex]


Question 1b


The other two angles of right triangle PQR are complementary.

This implies that,



[tex](5x + 20) + 3x = 90 \degree[/tex]


We group like terms to get,


[tex]5x + 3x = 90 - 20[/tex]


This implies that,


[tex]8x = 70[/tex]


[tex]x = \frac{70}{8} [/tex]


[tex]x = 8.75[/tex]


Question 1c

We substitute the value of x to determine the


value angle QRP.


[tex] \: < \: QRP = 5(8.75) + 20 = 63.75 \degree[/tex]

Question 1d

We substitute the value of x to determine the value angle RPQ.


[tex] \: < RPQ \: = 3(8.75) = 26.25 \degree[/tex]
