Question

Pls help me asap TYYeven just one of them :))​

Answer 1

Find length FD

FD is Opposite

BD adjacent

O + A is Toa

Tan20 = o/9

x9

9 x Tan20 = o

O = 3.2757.... (ans)

Opposite/ FD is 3.28cm to 2.p.d

Draw diagonal line from A to D & find its length - that's the hypotenuse of a right-angle created

Use Pythagoras Theorem

a^2 + b^2 = c^2

25^2 + 9^2 = c^2

Square root both sides to get c

C = root 25^2 + 9^2

= root 706

= 26.57066...(ans)

AD is 26.57cm

Now create another right-angle triangle A to F to D back to A.

Label dimensions found such as the Length of AD to be 26.57.. Plus, FD to be 3.28.

Use trig for angel FAD:

Opposite of triangle is 3.28

Adjacent is 26.57

So, OA means Toa, but we're after an angle & have to use tan inverse instead.

Tan-1 (3.28/26.57) = 7.0374..

So, the angle is 7.04 degrees.

(ans) - ignore, I did use rounded figures in my ans, I was originally not going to, but I did.

Hope this helps!
