Answer:
Step-by-step explanation:
To solve for the leg of the missing right triangle, one must use the Pythagorean theorem. The Pythagorean theorem states the following,
Where (a) and (b) are the sides adjacent to or next to the right angle. (c) is the side opposite the right angle. Substitute in the given values and solve for the unknown,
Substitute,
Simplify,
Inverse operations,
Perform the indicated operation.
-8 + (-4) = -12
Steps:
-8 + ( -4 )
Remove Parenthesis:
( -a ) = -a
-8 - 4
Subtract the numbers:
-8 - 4
= -12
Answer: -8 - 4 = -12
Hope that helps!!!! : )
Yup that is correct, that is the way to convert measurements of angle from radians to degrees. because 2pi is equivalent to one revolution of a circle and in degrees is equal to 360 degrees, then simplifying it 360 / 2pi = 180 / pi.
so <span>the measure of 0 is A radians and B degrees, then A = 180 B/pi</span>
Put the given information into the formula and solve for the variable of interest.
.. V = π*r^2*h
.. 252π = π*r^2*7
.. (252π)/(7π) = r^2
.. 36 = r^2
.. 6 = r
The radius is 6 cm. Selection D is appropriate.
