Answer:
x=10
A = 84
Step-by-step explanation:
A and B are supplementary angles so they add to 180 degrees
A + B =180
2x+76 + 5x+34 = 180
Combine like terms
7x+ 110 = 180
7x+110-110 = 180-110
7x = 70
Divide by 7
x = 10
Now find A
A = 5x+34
A = 5*10 +34
= 50+34
A = 84
Answer:
x=10
A=84
Step-by-step explanation:
A+B=180
5x+34+2x+76=180
7x+110=180
7x=70
x=10
A=5x+34=5*10+34=50+34=84

Step-by-step explanation:
It is 57/8 ! You should use this math calculater! it's called calculater soup!
Multiply both sides of this fraction by i to cancel out the i in the denominator.
8 * i = 8i
3i * i = 3i^2 = -3
-(8i/3) is the simplified expression.
D = T2 - T1
d = 9 - 14
d = - 5
T40 = 14 + 39(-5)
= 14 - 195
= - 181
