Option B: 13.9 is the value of y
Explanation:
Given triangle is a right angled triangle.
The legs of the triangle are 8 and y.
The hypotenuse of the triangle is x.
And the angle opposite to y is 60°
We need to determine the value of y.
Let us find the value of y using the tangent formula.
The formula for tan is given by

Since, we know that
,
and 
Substituting these values in the formula, we get,

Multiplying both sides by 8, we have,

Substituting the value of
, we get,

Simplifying, we have,

Rounding off, we get,

Thus, the value of y is 13.9
Hence, Option B is the correct answer.
the decimal expansion is 0.31818181818182
Its being dilated by 3 therefore your answer is 9.9
Answer:
18x^2 + 12x - 6
Step-by-step explanation:
(6x - 2) (3x + 3 )
= 18x^2 + 18x -6x - 6
= 18x^2 +12x - 6
Answer:
b= 5
c = 10, x=7 hypotenuse = 7
Step-by-step explanation:
A 30-60-90 triangle has the ratios of x-x
-2x so if x=5, then 5-5
- 10
for a 45-45-90, if one leg is 7, so is the other x
so hypotenuse is 7
