Answer:
x = 6
y = 3
Step-by-step explanation:
Give triangle is a right triangle.
By applying sine ratio in the given triangle,
sin(60)° = 
x = 6
Now we take the cosine ratio in the given triangle,
cos(60)° = 
y = 
y = 
Therefore, x = 6 and y = 3 will be the answer.
Step-by-step explanation:
Since the 2 side lines are parallel,
(Note that you can further simplify the equation if you wish to, this is a general equation.)
(Equation formed due to Corresponding angles and Sum of angles on the same straight line)
Area = 3.14*(12.5^2 - 3.5^2)/4 =113.04
Answer is B
Answer:
20 and 10
Step-by-step explanation:
The formula for x in terms of w is x = 3w² and the formula for y in terms of x is y = (1/112)x³
<h3>Variation</h3>
x = k × w²
w = 4, x = 48
48 = k × 4²
48 = k × 16
48 = 16k
k = 48/16
k = 3
So,
x = k × w²
x = 3 × w²
x = 3w²
y = k/x³
x = 2, y = 14
14 = k / 2³
14 × 2³ = k
14 × 8 = k
112 = k
So,
y = k/x³
y = 112/x³
y = (1/112)x³
