Answer:
98 degrees
Step-by-step explanation:
the full degree of a triangle is 180 degrees
52 + 30 = 82
180 - 82 = 98
Right triangle bc a^2+b^2=c^2. (Pythagorean theorem)
When a line is given in the form

The slope of the line is m. So, in this case, the slope of
is 1.
Given a slope
, you find the slope of a perpendicular line
by imposing

So, if the given line has slope 1, a perpendicular line has slope
given by

and thus 
So, we want a line with slope -1 and passing through (12,-1). Using the fomula

we get

Answer:
18.85 rounded
Step-by-step explanation:
The length of an arc depends on the radius of a circle and the central angle Θ. We know that for the angle equal to 360 degrees (2π), the arc length is equal to circumference. Hence, as the proportion between angle and arc length is constant, we can say that:
L / Θ = C / 2π
As circumference C = 2πr,
L / Θ = 2πr / 2π
L / Θ = r
We find out the arc length formula when multiplying this equation by Θ:
L = r * Θ
Hence, the arc length is equal to radius multiplied by the central angle (in radians).
