Step-by-step explanation:
you cant simplify a hole number
Answer:
A
Step-by-step explanation:
The sum of the 3 angles in a triangle = 180°
Subtract the sum of the 2 given angles from 180 for third angle
third angle = 180° - (39 + 56)° = 180° - 95° = 85° → A
Answer:
A 31.5
Step-by-step explanation:
15x2=30 and A is the only one close to 30
Subtract 100 from both sides
50x = 150 + 30x - 100
Simplify 150 + 30x - 100 to 30x + 50
Subtract 30x from both sides
50x - 30x = 50
Simplify 50x - 30x to 20x
20x = 50
Divide both sides by 20
x = 50/20
Simplify 50/20 to 5/2
<u>x = 5/2</u>
<em>In decimal: 2.5</em>
