Answer:
FD= 1.6 ft
Step-by-step explanation:
Seems like an easy trig question so let's get to it.
1) Draw the right triangle to make it easier to solve (right triangle because we have a 90 degree angle)
2) Find the last angle measure by adding 90+70= 160 and 180-160= 20 so the last angle measure is 20.
3) Use trig function, tan20= x/4.4 to find the answer of x (FD) to be 1.6. Therefore, the FD value will be 1.6 ft.
Answer:
1.6
Step-by-step explanation:
( i submitted it and got it correct, this is the copy and pasted work it shows )
tanD=

4.4
\tan 70=\frac{4.4}{x}
tan70=
x
4.4
x\tan 70=4.4
xtan70=4.4
Cross multiply.
\frac{x\tan 70}{\tan 70}=\frac{4.4}{\tan 70}
tan70

4.4
Divide each side by tan 70.
x=\frac{4.4}{\tan 70}=1.6015\approx 1.6\text{ feet}
x=
tan70
4.4
=1.6015≈1.6 feet
