-7
+6
+2
+5
+9 that’s the answer
Answer:
Step-by-step explanation:
So to find the answer you need to use SOHCAHTOA
Sine= Opposite/ Adjacent
Cosine= Adjacent/Hypotenuse
Tan = opposite/adjacent
angle ADC is 60 so to find the length of line ABC we would use the angle and the line DC.
We would use Tan with opposite over adjacent
Tan 60 = opp. / 5 root 3
opp. = 15
so that is the length of the entire thing, all you need to do now is find the length of the single line of BC which we can use the same equation with just Tan 30 now.
Tan 30 = opp. / 5 root 3
opp. = 5
next you need to take the entire ABC length and subtract the length of BC to get AB
15-5 = 10
so the answer would be C
61/100-7/25 ••• First, find a common denominator. In this case, that would be 100
61/100-28/100 ••• Then, subtract the numerators
33/100 would be your solution.
