Answer:
6x
Step-by-step explanation:
8x-2x
Answer:
828
Step-by-step explanation:
Missing leg of triangle:
√15²-12²= √225-144=√81=9
Triangle faces= 2*1/2*12*9= 108
Base= 20*9= 180
Front face= 20*15= 300
Back face= 20*12= 240
Total= 108+180+300+240= 828
Second choice
The angle between 0° and 360° that is coterminal with -160° is 200 degrees.
<h3>What are coterminal angles?</h3>
Two different angles that have identical starting and ending edges are termed coterminal angles however since one angle is measured clockwise and the other is determined counterclockwise, the angles' terminal sides have completed distinct entire rotations.
It is given that:
The angle is -160 degrees
An example of a positive coterminal angle would be 360-160=200 degrees since angles always travel either counterclockwise or clockwise from the +x axis.
There can be an unlimited number of rotations and hence infinite coterminal angles because there is no range.
= -160 + 360 = 200 degrees
= 200+ 360n
= -160 - 360n degrees
Thus, the angle between 0° and 360° that is coterminal with -160° is 200 degrees.

Capital letters that have rotational symmetry are: Z, S, H, N and O. The letters Z, S, H and N, when rotated 180 degrees clockwise or counterclockwise, will look the same after rotation completion.
Hope it helps you my dear :)
