Answer:

1st Angle - 60

2nd Angle - 20

3rd Angle - 100

Step-by-step explanation:

Not sure if it really needs an explanation. 60 is 3 times as much as 20, and 100 is 80 more than 20. All together, it makes 180 degrees.

The base of an isosceles triangle is one and a half times the length of the other two sides. A smaller triangle has a perimeter
stira [4]

Answer:

P = 1.5x.

Step-by-step explanation:

Let the length of each side of the first triangle be x, then

Perimeter of this triangle

= 2x + 1.5x

= 3.5x.

So perimeter of smaller triangle is:

P = 1/2 * 3.5x

P = 1,.5x.
