Someone pls help me ill give out brainliest pls don’t answer if you don’t know
iren [92.7K]

Answer:

Step-by-step explanation:

The area of a sector has the formula

A_s=\frac{\theta}{360}*\pi r^2 Hopefully, this looks somewhat familiar to you. Theta is the central angle given as 75, r is the radius given as 4. Filling in:

A_s=\frac{75}{360}*(3.14)(4)^2 and simplifying that a bit to look less threatening, but not by much:

A_s=\frac{5}{24}(3.14)(16) and

A_s=\frac{251.2}{24}=\frac{157}{15}=10.466666666... Not sure how you're supposed to express your answer so I gave both the fraction and its decimal equivalency.

The two legs (labeled x) of the right triangle below have equal length. If the hypotenuse has length 5√2 , solve for x.
leonid [27]

Answer:

x=5

Step-by-step explanation:

Other than using the plain special aspect of a 45-45-90 triangle where the legs are x, x, and x√2, you can solve for this.

Since the two legs have equal length, they are both x. Using the pythagorean theorem:

(x^2)+(x^2)=50 (Because 5 squared is 25 and √2 squared is 2, multiplying them gives you 50).

You can add (x^2) and (x^2) because they are the same terms (x squared).

Simplifying like so gives you:

2x^2=50

Dividing by two on both sides:

x^2=25

Taking the square root of both sides:

x=5
