Answer:
Angle A = 102°
Angle B = 51°
Angle C = 27°
Step-by-step explanation:
angle A = 2b
angle B = b
angle C = 1/3 b + 10
Angle A + Angle B + Angle C = 180
2b + b + 1/3 b + 10 = 180
3 1/3 b + 10 = 180
10/3 b = 170
b = 51
a = 2b = 102
c = 1/3 b + 10 = 1/3 (51) + 10 = 17 + 10 = 27
Answer:
3b/20+4
Step-by-step explanation:
-2 + 2/5b - 1/4b + 6
Combine 2/5b and 1/4b to get 3/20b
-2 + 3/20b + 6
Add −2 and 6 to get 4.
4+3/20b
Answer:
c = 2 or c = -2

Answer:
The value of x is:

Step-by-step explanation:
we have to use the quadratic formula to solve for x.
The equation is given as:

which could also be written as:

The quadratic formula for the quadratic equation of the type:
is given as:

Here we have:
a=4, b=-5 and c=8.
Hence, by the quadratic formula we have:

Hence, the value of x is:

Answer:
b
Step-by-step explanation:
the y axis is the axis going up and down, so the reflection would be on the other side of the axis.
