The two base angles of an isoceles triangle are equal so we can conclude that
2x - 20 = x + 8
Now we just need to solve for x:
2x - 20 + 20 = x + 8 + 20
2x = x + 28
2x - x = x + 28 - x
x = 28
So, angle B = x + 8 which is 28 + 8 = 36°
If three dozens took 15 minutes that five minutes a dozen and with six dozens it would be 30 minutes
Answer:
x = 3
Step-by-step explanation:
A proportion is two fractions that are equal.
Reduce both fractions. If they are equal, then it is a proportion.
12/22 = 6/11
18/33 = 6/11
The fractions are equal, so they do form a proportion.
(6/4) (2/3) times the denominators (4x3=12) then times (6x3 and 4x2) add the two answer together which should be 26/12 then reverse it. 12/26 = 6/13 (I'm English so might be different for you)
