66.7 is the answer i believe
Hello from MrBillDoesMath!
Answer:
96 degrees
Discussion:
The base angles of an isosceles triangle are equal and a triangle has 180 degrees. In our case this means that
42 + 42 + (measure of vertex angle) = 180
84 + (measure of vertex angle) = 180 => (subtract 84 from both sides)
84 - 84 + (measure of vertex angle) = 180- 84 =>
(measure of vertex angle) = 180- 84 = 96
Thank you,

Answer:
x = 2
Step-by-step explanation:
6-4x=6x-8x+2
6 - 4x = -2x + 2
6 - 2 = -2x + 4x
4 = 2x
2x = 4
x = 4/2
x =2
Answer:
Kate's sister is 5
Step-by-step explanation:
(k = kate's age)
(s = sister's age)
k = s + 3
k + 2 = 2s
Rearrange k + 2 = 2s into and plug it into the first equation
k = 2s - 2
2s - 2 = s + 3
2s - s = 3 + 2
s = 5
Statistics are based on true facts. This is not a statistical question because someone may answer “no” if they want to be silly.
You already know that everyone you ask is in 6th grade so there is no point in asking because anyone who says no is lying.
