Answer:
65°
Step-by-step explanation:
All triangles equal 180 degrees. So just subtract the other values.
Answer: At least 13
Step-by-step explanation:
You lose 20%.
if it were going up to 72 to 90 it would be a 25% increase
For this case what we have to take into account is the following variable:
x = represent the unknown number
We now write the following inequality:
"four times the sum of number and 15 is at least 20"
4 (x + 15)> = 20
We clear the value of x:
(x + 15)> = 20/4
(x + 15)> = 5
x> = 5 - 15
x> = - 10
The solution set is:
[-10, inf)
Answer:
all possible values for X are:
[-10, inf)
Answer:
-11
