Answer:
200√3
Step-by-step explanation:
The triangle given here is a special right triangle, one with angles measuring 30-60-90 degrees. The rule for triangles like these are that the side opposite the 30° angle can be considered x, and the side opposite the 60° angle is x√3, while the hypotenuse, or side opposite the right angle, is 2x. All we need to know here are the two legs to find the area.
Since b is opposite the 30° angle, it is x, while side RS is opposite the 60° angle, meaning it is equal to x√3, meaning that the area of the triangle is 1/2*x*x√3. We can substitute in 20 for x, making our area 1/2*20*20√3. Multiplying we get 10*20√3, or 200√3.
Answer:
$40.95
Step-by-step explanation:
daniel earned 18.20 for working 2 1/3 hours
so he earned 18.20 / (2 1/3) for each hour of work
for 5 1/4 hours of work, he earned
= 18.20 / (2 1/3) x 5 1/4
= $40.95
Step-by-step explanation:
Increase in price = R6 - R5 = R1
% increase. =. R1÷R6 × 100 = R0.16 ×100%
% increase. = 16%

Answer:
(x, y) = (34/5, -4/5) = (6.8, -0.8)
Step-by-step explanation:
Subtract the first equation from the second to eliminate x.
Substituting for y in the second equation, we can find x.
The solution is (x, y) = (34/5, -4/5) = (6.8, -0.8).
