thanks!!!

Answer:

the angles are 45, 45 and 90.

since 2 angles are equal and one of the angles are 90 degrees, the triangle is a right angled, isosceles triangle.

Step-by-step explanation:

this is an isosceles triangle because two of the angles are equal.

also, by calculating the angles through the method given below, we can tell that the triangle is also a right angled triangle.

first, we multiply all three terms of the ratio by an unknown number: n

9n + 9n + 18n = 180

(the sum of all angles of a triangle is 180)

36n = 180

n = 180/36

n = 5

9n = 45

18n = 90

the angles of the triangle are 45, 45 and 90.
