Answer:
B. 103°
Step-by-step explanation:
Supplementary angles add up to 180°, so we can find the measure of angle 2 by subtracting 77 from 180
180 - 77
= 103
So, m∠2 is 103°
All I know is 5 and 6.
5. -7 (the picture is the model to draw)
6. -5
Hi there!

First we need to work out the parenthesis, which can for instance be done using rainbow technique.

Now subtract 3 from both sides.

And finally add 3x to both sides.

The 4th answer choice is correct.
the two triangles are congruent
P3(4) = p12 them p12 * p8 = P160 (false)
