Isosceles triangle, angle P = angle Q.
3x + 10 = x + 52
2x = 42
x = 21
Congruent angles are both x+52=73 degrees. Triangle angles add to 180 so
y = 180 - 73 - 73 = 34 degrees
Answer: 34
The answer is 17 1/4 .Hope this helped.
Answer:
-3<x<3
Step-by-step explanation:
let y=0
0=x^2-9
0=(x+3)(x-3)
x=-3 and x=+3
Answer: 60
Step-by-step explanation:
Since AB and BC creates AC, we can add them together to find x, then use that to find the value of BC.
8x+9+6x+6=141 [combine like terms]
14x+15=141 [subtract both sides by 15]
14x=126 [divide both sides by 14]
x=9
Now that we have found the value of x, we can plug that into BC.
6(9)+6 [multiply]
54+6 [add]
60
Now, we know the length of BC is 60.
