Answer:
(180-14):2= 166:2= 83° (smaller angle)
(180-14):2+14= 166:2+14= 83+14= 97° (bigger angle)
As we know a percentage is out of a hundred so we would start of by dividing by 100, if the percent is not a whole number then multiply both the bottom and top number by 10 for every number after the decimal point
100000 x 10000
Answer to equation if needed: 1000000000
<ADB=20
<ADC=55
<BDC=32.5
<ACB=20
You know 11% as decimal is 0.11 so you multiply 0.11 and $121.65 which is 13.38 so c is the correct answer rounded to the nearest hundredth
