Acute Triangle

Step-by-step explanation:

Angles in a triangle add up to 180 degrees.

So,

x+2x+2x = 180

=> 5x = 180

Dividing both sides by 5

=> x = 36

So, The lengths are:

=> 36

=> 72

=> 72

Since all the angles are less than 90 degrees, It is an acute triangle.

$25

step-by-step explanation:

25 - 4.50 = 20.5

20.5 / 2 = 10.25

10.25 + 10 = 20.25

20.25 - 12.50 = 7.75

therefore the answer is $25 as shown as the first number.
