Answer:

Step-by-step explanation:
Simplify:
45 = 5 * 3 * 3
60 = 5 * 3 * 2 * 2
GCF = 5*3 = 15


its B. 50°
Triangle Have 180°
- 180 - 90 = 90
- 90 × 2 = 180
Half of triangle Have 90°
Answer:
Step-by-step explanation:
Her former rent is $ x
Twice the former rent: 2*x = 2x
$300 less than 2x: 2x - 300
2x - 300 = 550
Add 300 to both sides
2x - 300 + 300 = 550 + 300
2x = 850
Divide both sides by 2
2x/2 = 850/2
x = 425
Her former rent = $425
<h3>Angles sum up to:</h3><h3>( n - 2 ) × 180 = ( 5 - 2 ) × 180 = 3 × 180 = 540</h3>
