15:13 is in its simplest form already, since 13 is a prime number and 15 is not a multiple of 13.
A + b + c = 180
a = 2b
b = c + 4
Substitute the b equation into the a equation
a = 2(c + 4)
a = 2c + 8
Substitute equations a and b into the first equation
2c + 8 + c + 4 + c = 180
4c = 168
c = 42
Find the other angles using c
b = 42 + 4
b = 46
a = 2(42) + 8
a = 92
Therefore angle a is 92 degrees, angle b is 46 degrees, and angle c is 42 degrees.
Answer:
<u>Savannah budgets the 40.97% of her income for Housing, 8.32% for Utilities, 20.02% for Transportation, 6.93% for Food, and 10.78% for Personal expenses.</u>
Step-by-step explanation:
<u>1. Housing. </u>
1330/3246 * 100 = 0.4097 * 100 = 40. 97%
<u>2. Utilities.</u>
270/3246 * 100 = 0 .0832 * 100 = 8.32%
<u>3. Transportation.</u>
650/3246 * 100 = 0. 2002 * 100 = 20.02%
<u>4. Food.</u>
225/3246 * 100 = 0. 0693 * 100 = 6.93%
<u>5. Personal.</u>
350/3246 * 100 = 0.1078 * 100 = 10.78%
