Hello from MrBillDoesMath!
Answer:
1/2
Discussion:
6/12 = => as 12 = 6*2
6 /( 6*2) = => cancel 6's in num and denom.
1/2
Thank you,
MrB
4w -1
Because 7w + -3w = 4w and then -6 + 5 = -1
13.1......... I believe this is the correct answer
Take a picture of the chart
Answers:
x = -3
base angle = 49 degrees
============================================
Work Shown:
The missing angle is (2x+55) degrees since the base angles are congruent.
Add up the three angles and set the sum equal to 180. Solve for x.
(82)+(2x+55)+(2x+55) = 180
4x+192 = 180
4x = 180-192
4x = -12
x = -12/4
x = -3
Use this x value to find the base angle
B = base angle
B = 2x+55
B = 2*(-3)+55
B = -6+55
B = 49 degrees
