Hello!
∠E and the angle measuring 119 degrees (we'll refer to this as ∠A) can be classified as supplementary angles. Supplementary angles are two angles whose measures add to a sum of 180 degrees (a straight line). Therefore, we can conclude that sum of ∠E and ∠A is 180 degrees. We can use this information to create the following equation:
∠E + 119 = 180
Now subtract 119 from both sides of the equation:
∠E = 61
We have now proven that ∠E is equal to 61 degrees.
I hope this helps!
First we must take the 4 to the other side: giving us -2x = 6.
Then we take the -2 to the other side:
X = 6/-2
X = -3
C^2 - 10c = 0
c^2 - 10c + 25 = 25
(c - 5)^2 = 25
c - 5 = sqrt 25
c = 5 (+-) sqrt 25
c = 5 (+-) 5
c = 5 + 5 = 10
c = 5 - 5 = 0
solutions are 0,10
Answer:
10 full hours (10.224 is exact)
Step-by-step explanation:
Answer: 16
its just x plus 1/3 of x. This is harder to find so youre probably not expected to find it this way.
Actual way to solve it.
set up proportion.
= 
cross multiply
3 x x = 3x
12 x 4 = 48
48 = 3x
divide by 3 to get x
48 / 3 = 16
x = 16
