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!

the answer is somewhere there guys it really . there im just not gonna answer

step-by-step explanation:

but i'm guessing ur first option tho

∞ this is your sign
