Answer:
first let's solve for x
x + (x + 30) + 2x = 180
4x + 30 = 180
-30 -30
4x = 150
/4 /4
x = 37.5
Now solve for the angle measures:
(x + 30) = (37.5 + 30) = 67.5
2x = 2(37.5) = 75
x = 37.5
8(hours)-5=67
8(h)-5=67
8h-5=67
8h=67+5
8h=72
H=72/8
h=9
Answer:
pi^4
Step-by-step explanation:
In a problem like this you subtract exponents
11 - 7 = 4
pi^4
Answer:
35
Step-by-step explanation:
Over b
84+8x=15x+140
Subtract 84 from both sides
8x=15x+56
Subtract 15x from both sides
-7x=56
Divide both sides by -7
x=-8
