The general rule for 90° counterclockwise rotation about the origin is given by:
(x,y)→(-y,x)
thus given that S has coordinates of (5,4), then rotation through 90° will map the the figure on S'(-4,5). Hence the answer is:
C](-4,5)

The area of the circle is 6,358.5cm²
<h3>Area of the circle</h3>
The formula for calculating the area of a circle is expressed as;
r is the radius = x + y
r = 25 + 20 = 45cm
Substitute the given parameters into the formula to have:
A = 3.14(45)²
A = 6,358.5cm²
Hence the area of the circle is 6,358.5cm²

Answer:
i think there are similars cause AC is equal to PR
Step-by-step explanation:
JMK’s angle is part of the right angle of JMN. The measurements there is 28°. A right angle is 90° so subtract 90 and 28 to get your angle measurement of JMK.
A small hint for the STR one is the fact that the straight lines are 180°. So Look at the line RTS. RTS is 180° by adding both the measurement of STR and STP. Simply subtract 180° with 118 to get STR.
