Find the length of the missing side. The triangle is not drawn to scale.

suter [353]

Answer:

D.) 8

Step-by-step explanation:

You can use the Pythagorean theorem because this is a right triangle:

$a^2+b^2=c^2$

a and b are the legs and c is the hypotenuse. The hypotenuse is always the longest side in a right triangle (since it is opposite the biggest angle). The two legs squared have to add up to the hypotenuse squared.

Fill in values:

$a^2+15^2=17^2$

Simplify exponents:

$a^2+225=289$

Isolate the variable. Subtract 225 from both sides:

$a^2+225-225=289-225\\a^2=64$

Find the square root of both sides:

$\sqrt{a^2}=\sqrt{64}\\ a=8$

The missing leg length is 8.

Find the circumference and length of the darkened part of the arc. Leave answer in terms of pi

Allisa [31]

Answer:

Circumference=16pi

Arc Length=8pi

Step-by-step explanation:

Circumference formula=2(pi)(r), or d(pi)

The arc is only half of that in this case, therefore you would only pi(r) or 1/2(d)(pi).
