Factor a square root of 14 out of every expression to get:



Thus, the expression is equal to four times the square-root of 14. The second answer is correct.
The two labeled angles are alternate exterior angles, and as such, they are equal. This means that we can set up and solve the following equation:

(3 - 2)(3 + 21) = 9 + 63 - 6 - 42 = 72 - 6 - 42 = 66 - 42 = 24 (I got 24 as my final answer)
Answer:
The value of x in the equation is 1.1
Step-by-step explanation:
7x = 7.7
Divide 7 on both sides of the equation.
x = 1.1
Flipping over the trigonometric functions of sine, cosine and tangent we have the following respectively
1/cscФ (sinФ), 1/secФ (cosФ) and 1/cotФ (tanФ). These are the identities for which they numerically equal when the numerator and denominator of these fractions are swapped.
