Step-by-step explanation:
Answer:
AB = 15 A = 36.9 B = 53.1
Step-by-step explanation:
A2 + B2 = C2
12(2 + 9(2 = 144 + 81 or 225 = C2
sqaure 225 to get rid of the exponent
so C = 15 or AB = 15
Divide your Oppisite by Hypo so 9/15 = .6
then use x = sin-1(0.6) to find angle A or 36.9
then add 36.9 to 90 and minus that from 180
so 180 - 126.9 = 53.1
Answer:
Biggest number = 13
Smallest number = 12
Step-by-step explanation:
x + y = 25... eqn 1
x - y = 1.... eqn 2
subtract equation 2 from 1
x + y = 25
-x - y = 1
---------------
2y = 24
divide both sides by 2
y = 24/2
y = 12
substitute y=12 into equation 2
x - 12 = 1
x = 12+1
x = 13
