Answer:
x = 44°
Step-by-step explanation:
Since this is an isosceles triangle, the other angle that isn't defined is also 68°. So, since all the angles add up to 180°,
x + 68(2) = 180
x + 136 = 180
x = 44°
Answer:
<u>$67.43 altogether</u>
Step-by-step explanation:
A 15% percent tip means 15% OF the bill.
15% of 58.65

You can't really pay $8.7975, so you would round to the nearest one hundredth which is $8.78.
Now you add the $8.78 to $58.65 which will give you $67.43.
I hope that helps!
Answer:
First we need to calculate the are of each wall, since we alredy knew the length (l) and the width (w) which is the height of the wall in this case:
A = wl = 9 . 12 = 108 (ft²)
We also know that he painted 3 walls, we need to multiply our first result by 3, in other words, the area of wall that Brett painted is the sum of the area of three walls: 108 . 3 = 324 (ft²)
It's C because the equations are similar
