Answer:
Step-by-step explanation:
25.
x + 2x -75 = 90
3x = 90+75
3x = 165
x = 55
Measure of A = 55
Measure of B = 2(55) - 75 = 110 - 75 = 35
28.
2x+10-x+55 = 90
x = 90-65
x = 25
measure of A = 2(25) +10 = 60
measure of B = -25+55 = 30
31.
2x+3+3x - 223 = 180
5x -220 = 180
5x = 400
x = 80
measure of A = 163
measure of B = 17
32.
-4x+40+x+50 = 180
-3x +90 = 180
-3x = 90
x= -30
measure of A = -4(-30) +40 = 160
measure of B = -30+50 = 20
Answer:
6in...8in...and...10in
Two sides must use the pythagoras theorem to obtain the hypothenus
square root of 8 squared plus 6 squared so as to obtain a 10...hence making it a right angled triangle
They didn’t use the distributive property correct because they didn’t multiply 5x3
Answer:
b - 9 = 2 I believe would be it
To find the area of the pools surface you multiply the length times the width of the pool
