Answer:
$16.50
Step-by-step explanation:
From the circle geometry theorem, a tangent to a circle makes 90° angles with the radius of the circle.
RQ is perpendicular to QP
Triangle RQP is a right-angled triangle
by Pythagoras theorem

units (rounded to one decimal place)
17/20 x -12/34 =-3/10
Multiply the top to top and the bottom to the bottom
then reduce it to the lowest term
Answer:
x° = 40°
Step-by-step explanation:
142° = 3x° + 22° (Vertically opposite angles)
3x° = 120°
x° = 40°
