Answer:
The measure of each angle:
152.8° and 27.2°
Step-by-step explanation:
Supplementary angles sum 180°
then:
a + b = 180°
a - b = 125.6°
then:
a = 180 - b
a = 125.6 + b
180 - b = 125.6 + b
180 - 125.6 = b + b
54.4 = 2b
b = 54.4/2
b = 27.2°
a = 180 - b
a = 180 - 27.2
a = 152.8°
Check:
152.8 + 27.2 = 180°
Answer:
7/x < 8y
Step-by-step explanation:
7/x < 8y
Answer:
B
Step-by-step explanation:
the equal is correctly
3x + 1 = 2x + 4
what was done now :
2 x-blocks (2x) subtracted from the right side, and 1 numbered block subtracted from the left side.
to reestablish balance and equality of both sides, we need to do more the exact same things - just in the other sides.
2 x-blocks subtracted from the LEFT side, and 1 numbered block subtracted from the RIGHT side.
and that is answer B.
