Answer:

27°

Step-by-step explanation:

Step 1:

∠A + ∠C + ∠D = 180°     Sum of a Δ

Step 2:

3x - 10 + 45 + 2x + 10 = 180        Input all values

Step 3:

5x + 45° = 180°     Combine Like Terms

Step 4:

5x = 135°        Subtract 45° on both sides

Step 5:

x = 135° ÷ 5       Divide

Answer:

x = 27°

Hope This Helps :)

ki77a [65]
See attached image

First, we must know this: Complementary angles are two angles whose sum is equal to 90°, while supplementary angles are two angles whose sum is equal to 180°. That been said, the only statement which is true is the second statement, <span>MNL is complementary to KNL

Reasons why others are False
</span>GNJ is supplementary to JNK, not complementary
MNG is supplementary to GNJ, not complementary
LNJ (not KNJ) <span>is supplementary to MNL
</span>GNM is equal to JNK, not supplementary
