Answer:
angle B: 39
AC: 7.288
AB: 11.58
(note: you cut off the part about rounding so make sure that it's rounded correctly before you put in your answer)
Step-by-step explanation:
To solve this we will use SOH, CAH, TOA
we have the angle and the one opposite to it which means we can use either SOH or TOA
let's use TOA
tan(51)=(9/x)
x= 7.288
We can now use pahtagaryous theroem to solve for the hyptonouse
we have
9²+7.288²=C²
C=11.58
Finally, to find angle B we will recall that the angles of a triangle must add to 180.
51+90+a=180
a=39
The answer is 15. Her daughter is 15 years old.
In order to find this we need to work backwards. First let’s subtract 2 from Frannie’s current age.
That gives us 45. We know that her daughter is 3 times younger so now all we need to do is divide by 3.
That gives us fifteen.
Hope this helped !!
