Answer:
142°
Step-by-step explanation:
Make a line parallel to RT to create alternate internal angles
<u>Since QS ║ MN, the following equations are true:</u>
The angle QSR is exterior of ΔSQT.
<u>Exterior angle measure is the sum of non-adjacent interior angles:</u>
Area of a square is side length^2
Area = 15^ 2 = 15 x 15 = 225 square inches.
16 + 20 or 2 x 18
+= 34
The equation of a circle in standard form is
+=
where (a , b) are the coordinates of the centre and r is the radius
The centre is at the midpoint of the endpoints and the radius is the distance from the centre to either of the 2 endpoints
Using the midpoint formula
midpoint = [(x+, (+
where (,=(3,8) and (,=(-7,2)
centre = ((3-7),(8+2)) = (-2,5)
Calculate r using the distance formula
r = √(-)²+(-)²)
= √((3+2)²+(8-5)²) = √(25+9) = √34 ⇒ r² =(√34)² = 34
equation of circle is : (x+2)²+(y-5)² = 34
