All angles add up to be 180 degrees, so:
1X+2X+3X=180
6X=180
X=30
smallest angle=30 degrees
medium angle=60
largest angle=90.
Answer:
D
Step-by-step explanation:
The time taken for the ball to fall a distance of 10feet is 1.25secs
Given the function modeled by the height expressed as:
f(t) =-16t² + 35
In order to determine the time taken by the all to fall a distance of 10 feet, hence;
f(t) = 10
10 = -16t² + 35
-16t² = 10 - 35
-16t² = -25
-t² = -25/16
t² = 25/16
t = √25/16
t = 5/4
t = 1.25secs
Hence the time taken for the ball to fall a distance of 10feet is 1.25secs

Answer:219.96 yd²
Explanation:The area of the trapezoid can be calculated using the following rule:Area of trapezoid =

where:
b1 is the length of the first base
b2 is the length of the second base
h is the height
Now, in the given we have:b1 = 15.8 yd
b2 = 21.8 yd
h = 11.7 yd
Substitute with the givens in the above equation to get the area as follows:area =

Hope this helps :)
