What is the length of ad¯¯¯¯¯¯¯¯? ad≈ enter your answer as a decimal rounded to the nearest hundredth.

First, you need to calculate the hypotenuse, this is possible because we know the value of one angle, 72 degrees, and one angle is 90 degrees.

sin72 = DC / AC , sin of an angle = opposite / hypotenuse

AC = DC / sin72, we must calculate the value of sin72 by calculator, and sin72 = 0,254

AC = 6/0,254 = 23,62

From here, we use the Pythagorean theorem to calculate AD, like such:

AD^2 = AC^2 - DC^2

AD^2 = 23,62^2 - 6^2

AD^2 = 557,90 - 36 = 521,9

AD = square root of 521,9

AD = 22,845 = 22,8

It seems a bit weird, but that's what the math says. Hope this helps!

i believe the answer is 68cm

step-by-step explanation:

i just took 34 x 2 because the space between v and y is the same as y to k.

logv3(x+2)=1

rewrite in exponential form:

logb(x) = y is equal to b^y =x

b = 3, y = 1

now solve for x:

3^1 = x+2)

x = 3-2

x = 1

see the picture for the graph.
