Answer:

$x=5$

Step-by-step explanation:

Similar Triangles

By looking at the construction of the figure, we can safely assume both triangles are similar, i.e. their internal angles are equal and their sides are proportional. Following the proportion of the heights and bases of both triangles we can set this relationship:

$\displaystyle \frac{45}{36}=\frac{5x}{20}$

Simplifying both fractions

$\displaystyle \frac{5}{4}=\frac{x}{4}$

Solving for x

$x=5$

If cos Θ = negative 4 over 7, what are the values of sin Θ and tan Θ?

FinnZ [79.3K]

Given cos theta is equal to - 4/ 7 then we can conclude that theta is in the second and third quadrants. In this case, the other leg is equal to square root of (7^2 - 4^2 ) equal to square root of 33. In this case, sin theta can be equal to +- square root of 33 / 7 and tan theta is equal to +-square root of 33 / 4.
