Question

The measures of the angles of a triangle can be represented by the expressions (2x), (3x-20), and (3x). What are the measures of the three angles?
a) 20, 30, 130
b) 36, 72, 72
c) 40, 60, 80
d) 50, 55, 75

Answer 1

can you attach a diagram of the triangle please?

Answer 2

There is no image of the diagram :/ thats why i dont get it either.

Answer 3

you can use the fact that the sum of the angles in any triangle is 180 degrees so you'd have the equation:
\(\large (2x)+(3x-20)+(3x)=180 \)
solve for x then plug that value in back to the expressions for the angles of the triangle.

Answer 4

sum of three angles in a triangle is 180 degrees
