Complete Question
In ΔVWX, w = 780 cm, ∠X =21° and ∠W=146°. Find the length of x, to the nearest 10th of a centimeter.
Answer:
499.9cm
Step-by-step explanation:
We solve for length x using the Sine rule
w/ sin W = x /sin X
Cross Multiply
x × sin W = w × sin X
x = w × sin X/ sin W
x = 780 × sin 21°/ sin 146°
x = 499.88 cm
Approximately to nearest tenth = 499.9cm
Answer:
every fraction is a rational number but a rational number need not be a fraction
It would equal 1
Explanation
- keep (keep first fraction the same)
- change (change division to multiplication)
- flip (flip the last fraction)
