Asap ! true or false? triangle fgh is a right triangle.

True

Explanation:

To determine if this is a right triangle, we see if the Pythagorean theorem works for these sides.

The Pythagorean theorem says that the sum of the squares of the legs of a right triangle is equal to the square of the hypotenuse; algebraically,

a² + b² = c²

The longest side will be the hypotenuse if this is a right triangle, and the other two will be the legs.

Plugging these into the Pythagorean theorem, we have

6²+(√45)² = 9²

Square root and squared cancel each other out, giving us

36+45 = 81

This is a true statement, so this is a right triangle.

smaller angle is 18

The larger angle is 54

Step-by-step explanation:

The ratio is 1:3

Multiply by x

x:3x

We know they sum to 72

x+3x = 72

Combine like terms

4x= 72

Divide by 4

4x/4 = 72/4

x =18

The smaller angle is 18

The larger angle is

3x = 3*18 =54

The larger angle is 54
