An isosceles triangle has congruent base angles, so if one of the base angles measure 54 degrees, then the other base angle does, too.
And a triangle measures up to 180 degrees.
180 = x + 2(54)
180 = x + 108
x = 72
So the answer is B) 72

And a triangle measures up to 180 degrees.
180 = x + 2(54)
180 = x + 108
x = 72
 B) 72 is right option

Jessica made 124 cookies. She put the cookies into three boxes, A, B and C.
Oxana [17]

There are 78 cookies in box C, 26 cookies in box B and 10 cookies in box A.

let the number of cookies in first box be represented mathematically as   B-16

the number of cookies in second box be represented as B

the number of cookies in third box be represented as 3B

Since there are 124 cookies we can make an equation  such that it becomes

B-16 +B +3B =124

Solving for B, we have

5B -16 =124

5B =124 +16

5B =130

B=130/5

B=26

Therefore Box A contains B-16 =26-16 =10 cookies

Box C contains 3B =3 X 26=78 cookies
