Answer:
KJM and KJH
Step-by-step explanation:
Supplementary angles are angles that equal 180 degrees
Answer:
x= -10
Step-by-step explanation:
................
The final answer would be 39/19 it doesn't simplify any more and if it did the 19 would be reduced as well as the 39
10.
Answer: 42° and 138°
Steps: First find value of x by adding both equations and setting them equal to 180°:
3x + 12x - 30 = 180
15x - 30 = 180
15x = 210
x = 14
Next, put value of x into equations to find the angle:
3x
3(14)
42°
12x - 30
12(14) - 30
168 - 30
138°
11. Answer: 28°
Steps: Complementary angles add up to 90°, so subtract 62° from 90° to find its complementary angle.
90 - 62 = 28
12. Answer: Corresponding angles are congruent.
Answer:
39 / 10
Step-by-step explanation:
3.9
= 3.9 x 10 / 10
= 39 / 10
