Answer:
103°
Step-by-step explanation:
Let's take the 3rd angle as θ:
Since all the angles in a triangle add up to 180°,
57 + 20 + θ = 180
77 + θ = 180
θ = 180 - 77
= 103°
Hence, the third angle is 103°

Answer:
C (y=5x-7)
Step-by-step explanation:
First, you find the slope between the 2 points which is 5, then you use one of the points to form an equation.
You then find it's y=5x-7.
Answer:
Step-by-step explanation:Perhaps somebody's asked this already, but I can't see it. Suppose I have a square that is 7 feet by 7 feet. I want to calculate the area. I multiply 7 feet by 7 feet and get 49 square feet, but since the lowest number of sig figs in one of my operands is one, my answer can only have one sig fig. This forces my answer to be 50 square feet, and I have now lost precision. Can somebody explain this?
The height will be 4 cm.
Explanation
<u />The volume of a cylinder is given by the formula V=πr²h. For a volume of 36π cm³ and a radius of 3 cm,
36π = π(3²)h
36π = 9πh
Divide both sides by 9π:
36π/9π = 9πh/9π
4 = h
Answer:
ur right
it's -1013
bc you need to do multiplication first so the equation turns out to be
10 - 1000 - 23
so then that turns to -1013 if you calculate left to right
