Question

CHECK FOR FAN AND MEDAL...
Find angle B-
A. 50°
B. 55°
C. 60°
D. 65°


D right?

Answer 1

No, that's incorrect.

Answer 2

3x + 1 + 2x - 1 + 40 = 180

Answer 3

.......................................................... dangit

Answer 4

You would set it up as 40 + (3x +1) + (2x - 1) = 180.
Combine like terms to give you 5x + 40 = 180.
Subtract 40, and divide by five giving you x = 28
Plug x into the equation for b, giving you 55

Answer 5

Solve for 'x'

Answer 8

you would be correct :)
Since the angle sum of a triangle = 180.
And we're given one angle = 40.
You'd subtract 180 - 40 = 140

140 degrees would be the total of angle A and angle B
Therefore, 3x + 1 + 2x - 1 = 140

Then solve for x.
So 5x = 140
Therefore x = 28

Then you'd substitute it back into Angle B ( 2x + 1)
and you'll get 55 degrees which is correct :)
