Answer:
Largest Face: 90 degree angle
Step-by-step explanation:
2 3/5 as improper fraction = 13/5
Let x be the 1st number
x + 9 be the second number
Equation:
x + x+9 = 171
Solution:
2x + 9 = 171
2x = 171 - 9
2x = 162
x = 81
x + 9 = 90
81 + 90 = 171
3+5=8
8/20 =.4
.4 goes to 40% bc you move the decimal over twice
