Answer:
x = 110
Step-by-step explanation:
all angles of the triangle MUST add up to 180 degrees.
45 + 65 = 110
180 - 110 = 70
since x is sittling on a 180 degree angle, the sum of 70 and x must equal 180 too
180 - 70 = 110
Answer:
The sprinkler can spread water in a radius of 24 feet.
Step-by-step explanation:
Since the sprinkler sends water in a circular pattern in order to find the distance at which it can spread the water we need to find the radius of the circle. The area of the circle is said to be 1808.64 and it's formula is given by:
area = pi*r²
1808.64 = 3.14*r²
r² = 1808.64/3.14 = 576
r = sqrt(576) = 24 feet
The sprinkler can spread water in a radius of 24 feet.
It's easiest to find numbers that add up to 10.
Try and add up 24 and 36 because you know that 6+4=10
so you get 6+4 and then do 20+30, add those together and you get 60
Then do the same for the other two numbers
8+2 and 40+20, add those together and you get 70
Add up 60 and 70 and you get 130 text messages.
100=100%
15=X
15/100 x 100= 15%
