Answer:
30 degrees
Step-by-step explanation:
Keep this in mind, ALL triangles must equal 180 degrees.
This is an acute triangle, hence one of the angles is 90 degrees. To find the other two angles, we must solve for x. Since we know the sum of all angles in this triangle must equal 180 degrees, we know for setting up our equation, all the angles should equal 180.

Now solve for x by isolating x

Our x is -7, now that we know that the numerical value of x is -7, replace x with -7 for angle A.
-7 + 37 = 30
<A is 30 degrees.
<u>Check your work</u>
Plug in -7 where you see x.

Turns out this was a 30-60-90 triangle. ✅
It will take 4 hours, this is because it said it adds 1000 after two hours, and it will add another 1000 two hours later which will give you your answer of four hours
Answer:
The slope is 
Step-by-step explanation:
Hi there!
We are given the points (0, 4) and (6, 13)
We want to find the slope of the line containing these two points
Slope (m) is the steepness of the line. When calculating from two points, you use the equation
, where
and
are points
Although we have what we need to find the slope, let's label the values of the points to avoid confusion and mistakes.

Substitute these values into the equation
m=
m=
Subtract
m=
Simplify
m=
The slope of the line is 3/2
Hope this helps!
