Answer:
The answer to the problem is C
Here we are finding x, given the angle and adjacent side. To find x we will use the function cos as cos = a/h.
So let's do cos(35°) = 15cm / x
cos(35°) = 0.8 (1 dp)
x = 15 cm / cos(35°)
x = 18.3 cm (1 dp)
The answer is B. 100/5=20 hope i helped
Add 8.1 to both sides to find x!
hope this helps :-)
