Answer:
Acute Triangle
Step-by-step explanation:
<u><em>Angles in a triangle add up to 180 degrees.</em></u>
So,
x+2x+2x = 180
=> 5x = 180
Dividing both sides by 5
=> x = 36
<u><em>So, The lengths are:</em></u>
=> 36
=> 72
=> 72
<em><u>Since all the angles are less than 90 degrees, It is an acute triangle.</u></em>
Answer:
120 y2
Step-by-step explanation:
The floor consists of a square and a triangle
area of square = 10² = 100 yd²
area of triangle = bh ( b is the base and h the height )
Here b = 4 and h = 10 , then
area = × 4 × 10 = 2 × 10 = 20 yd²
company needs 100 + 20 = 120 yd²
-4y = 8x
y = 8x/-4
y = -2x
The constant of variation is -2
Answer: 5x-15=10
5x=25
x=5
Step-by-step explanation: i showed the steps above. i hope you can understand it and this helps :) *the very first step is to distribute the 5 to everything in the parentheses
