The conversion factors are 42 gallons in a barrel
4 quarts = 1 gallon. I use unit analysis to get answers for questions like these.

All the units are in the numerator. There are 120 * 42* 4 = 20160 quarts in 120 barrels.
X=22. The supplementary angle is 90°, so the 66° angle, plus (x+2) has to add up to 90° too.
Let complementary angle be x,
Then the other angle is 4x
x + 4x = 90 ( complementary angles)
5x = 90
x = 90/5
x = 18,
The measure of the smaller angle = 18
And the measure of the larger angle = 4x
= 4 * 18
= 72
The supplementary of the larger angle is,
Let y be the other supplementary angle.
72 + y = 180 ( Supplementary angles)
y = 180 - 72
y = 108.
Hence, the other supplementary angle is 108 degrees.
Hope you understood. Plzzz let me know if you have any doubts.
-2 is the answer when i figured out the problem
Answer:
Rotation then reflection
Step-by-step explanation:
The triangle starts where the light green one is. Then it is rotated 90 degrees clockwise around the point where the hypotenuse and longer leg meet. From the sark green triangle it is reflectd to where the purple triangle is.
