PQRS is a rectangle with a length of 10 inches and a width of 4 inches. What is the measurement of angle A, the angle formed by
2 answers:
Answer:
21.8°
Step-by-step explanation:
The two sides of the rectangle, 4 inches and 10 inches, make the legs of a right triangle that includes angle A.
The 4 inch side is opposite angle A and the 10 inch side is adjacent to angle A; this gives us the ratio for tangent:
To find the value of angle A, take the inverse tangent of each side:

Hi there!
Linear equations are typically organized in slope-intercept form: where <em>m</em> is the slope and <em>b</em> is the y-intercept (the value of y when x=0).
<u>1) Determine the slope (</u><u><em>m</em></u><u>)</u>
where two points that fall on the line are
and
Plug in the given points (4, -6) and (0, 2):
Therefore, the slope of the line is -2. Plug this into :
<u>2) Determine the y-intercept (</u><u><em>b</em></u><u>)</u>
The y-intercept occurs when x=0. We are given that (0,2) falls on the line, so therefore, 2 is the y-intercept. Plug this into :
