Answer:
a. p = 6
b. q = 4
c. r = 8
d. s = 10; t = 8.3
Step-by-step explanation:
1. a. The side length of two similar triangles are proportional, therefore:
Cross multiply
Divide both sides by 15
p = 6
b. Based on the midsegment theorem,
c. The side length of two similar triangles are proportional, therefore:
Multiply both sides by 20
r = 8
d. The side length of two similar triangles are proportional, therefore:
Multiply both sides by 6
s = 10
Multiply both sides by 5
t = 8.3 (nearest tenth)
X - 6y=18
2x-3y=9 |*-2
x -6y=18
-4x+6y=-18
----------------
-3x=0, x=0
2x-3y=9
2*0-3y=9
-3y=9, y=-9/3, y= -3
