Answer:
C
Step-by-step explanation:
Using the sine ratio in the right triangle.
sinC = = = , thus
∠ C = ( ) ≈ 34.85° ( to 2 dec. places )
x = 5
3 = x/ 3 + 4
This is same as
3/1 = x/ 3 + 4
Then cross multiply
1(x + 4) = 3× 3
x + 4 = 9
x = 9 - 4
100% - 70% = 30%
30% of what = £33.60?
Let p = original price
0.30p = 33.60
p = 33.60 ÷ 0.30
p = £112
exact form:
x= 3/5
Decimal form:
x=0.6
