Answer:
x = 28.8
Step-by-step explanation:
Using the Sine rule in the triangle then
= 
( cross- multiply )
x × sin87° = 43 × sin42° ( divide both sides by sin87° )
x = 
= 28.8
Answer:
To turn this equation into a fraction, convert both numbers into a fraction when multiplying.
Step-by-step explanation:
-7 = -7/1 or 7/-1
7/-1 * -3/5 * 15/7
- Multiply numerators and then multiply denominators and then simplify
(7*-3* 15)= -315
(-1*5*7) =-35
-315/-35=9
