Answer:

y=20º

Step-by-step explanation:

since the triangle is an isosceles triangle,

(5x)º=25º

25+25=50º

180º-50º=130º

3y+70º=130º

130-70=60º

3y=60º

y=60/3

y=20º

Answer:

  • y = 20

Step-by-step explanation:

We know that:

  • The given triangle is an isosceles triangle because its two legs are the same length.
  • 25 = 5x

First, let's find the value of x.

  • => 25 = 5x
  • => 25/5 = 5x/5
  • => x = 5

Now, let's use the triangle property to solve for y.

  • 3y + 70 + 25 + 25 = 180
  • => 3y + 120 = 180
  • => 3y = 180 - 120
  • => 3y = 60
  • => y = 20

Hence, the value of y is 20.
