Step-by-step explanation:
Answer:=3a+2b−21
Step-by-step explanation:
Let's simplify step-by-step.
3a+2b−7−4−10
=3a+2b+−7+−4+−10
Combine Like Terms:
=3a+2b+−7+−4+−10
=(3a)+(2b)+(−7+−4+−10)
=3a+2b+−21
We know angles 3 and 4 = 123°. We also know that they are both located on a straight line, which is 180°. If we subtract 123 from 180, we get 57°, which is the size of the two angles in the smaller triangle KTL is located in.
Now, if we add up all the angles of a triangle, we get 180. With that knowledge, we can subtract 114° (57 x 2) from 180 and get out answer, which is 66°.
