i am getting cos(32) but its not an answer choice @Loser66

2. Loser66

you use pythagoras to find AB and $$AB=\sqrt{89}$$ , right?

3. anonymous

yea

4. Loser66

hence $$cos(A)=\dfrac{8}{\sqrt{89}}$$

5. anonymous

oh i forgot that

6. anonymous

0.661 what i get now

7. Loser66

nope

8. Loser66

Carefully hit the calculator, it is 0.847998304

9. anonymous

yea thats what i got then its the cos of that

10. Loser66

that is the answer. That is cos of A = 0.847998304

11. Loser66

Read the question. It is "Find the VALUE of cosine of $$\angle A$$"
