Answer:
See below.
Step-by-step explanation:
5a)
In an isosceles triangle, the angles opposite the congruent sides are congruent.
m<A = 40 deg
m<B = 40 deg
m<A + m<B + m<C = 180
40 + 40 + m<C = 180
m<C = 100 deg
5b)
In a right triangle, one angle is a right angle.
m<A = 40 deg
m<B = 90 deg
m<A + m<B + m<C = 180
40 + 90 + m<C = 180
m<C = 50 deg
Three x plus fifteen equals twenty seven
3x + 15 = 27x

Both equations are equal to y, so set them equal to each other forming an equation in x
2x+4=x-3
-x -x
1x+4= -3
-4 -4
x= -7
You just plug in the value of x which is -7
Y= -7-3
Y= -10
