10+25+15 = 50 minutes
25 minutes for lifting weights
25/50 = 1/2
<span>let the angles be x and y.
as they are compliment
x+y=90
also given
x=7y
substituting value of x in first equation
7y+y=90
8y=90
therefore
y=11.25
x=7*y=78.75</span>
Triangle Perimeter: Add up the sides of the triangle.
26 + 24 + 10 = 60
The triangles perimeter is 60.
Triangle Area: height * base divided by 2
10 * 24 = 240
240/2 = 120
The triangles area is 120.
Answer:
Step-by-step explanation:
1/2a+20=50
1/2a=30
a=10
81 because 81 is a perfect square and 27 times 3 =81
