Step-by-step explanation:
Using SOH CAH TOA
Sin =opposite/hypotenuse
that means opposite=2
Hypotenuse=3
Cos=Adjacent/Hypotenuse
Using Pythagorean theorem
Hyp^2=Opp^2 +Adj^2
3^2 =2^2+adj^2
9=4+adj^2
9-4=adj^2
5=adj^2
Taking the square root of both sides
√5=adj
:: cos=√5/3
Answer:
3.7 million
Step-by-step explanation:
14,100,000 = 3,000,000 + 3p
3p = 11,100,000
p = 11,100,000 / 3
p = 3,700,000
X=15
Just divide 5x by 5 and 75 by 5
Makes no sense.
