Question

An isosceles triangle in which angles B and C have the same measure is shown. Find the measure of each angle whose degree measure us represented with variables. Angle A: x+8y-1 Angle B: 3y+4 Angle C:7x+5

Answer 1

3y + 4 = 7x + 5

and

x + 8y - 1 + 3y + 4 + 7x + 5 + 180

Answer 2

x + 8y - 1 + 3y + 4 + 7x + 5 = 180

Answer 3

y = -4/11 (-43+2 x)

Answer 4

x = 5

Answer 5

3y + 4 = 35 + 5

3y = 36

y = 12

Answer 6

that is right.

Answer 7

angle A is 100 degrees
angle B is 40 degrees
angle C is 40 degrees

Answer 8

thanks, now let me study the steps

Answer 11

Do you understand?

Answer 12

not

Answer 13

It's given that B = C, right?

Answer 14

x + 8y - 1 + 3y + 4 + 7x + 5 = 180 show
work please

Answer 15

the sum of all angles in a triangle is equal to 180

Answer 16

true

Answer 17

collect like terms

8x + 11y + 8 = 180

Isolate one variable first

Answer 18

then substitute that into the equation
3y + 4 = 7x + 5
