If angle I is congruent to angle K find the perimeter of triangle JIK?

inessss [21]

The perimeter of a triangle is given by <em>the sum its three sides</em>, then according to the figure above we have that:

$P=(7x-5)+(6x-5)+(9x-11) \\ \\ \therefore P=22x-21$

Thus, our goal is to find the value of $x$ and by finding it we will get the perimeter of the triangle. If ∠I = ∠K = β, then according to the Law of Sines we have:

$\frac{9x-11}{sin \beta}= \frac{6x-5}{sin \beta} \\ \\ \therefore 9x-11=6x-5 \\ \therefore 3x=6 \therefore \boxed{x=2}$

Lastly, the perimeter is:

$P=22(2)-21 \rightarrow \boxed{P=23 \ units}$

A. pi + 1 = 4.1415
B. square root of 24 = 4.8989
C. q/2
D. 4.222

Judging by these, we can conclude that the highest value is that of B. I hope this helps!

4. A cone has a height of 4 and a base area of 9pi. What is it's volume? <br><br> Show work

OLEGan [10]

V= 1/3 times pi times radius squared times height

V= 1/3 • 3.14 • 4.5 squared • 4(4.5 because 9 divided by 2)

V= 1/3 • 3.14 • 20.25 • 4

V= 1.0466 • 81

V= 84.7746 units cubed

If told to round to nearest tenth then 84.8 , if hundreds then 84.78
