What is the measure of z? 3 27 y x z

Sholpan [36]

Answer: $3\sqrt{10}$

Step-by-step explanation:

By the geometric mean theorem,

$\frac{y}{3}=\frac{27}{y}\\y^{2}=81\\y=9$

So, by the Pythagorean theorem,

$3^{2}+9^{2}=z^{2}\\90=z^{2}\\z=\boxed{3\sqrt{10}}$

What is cos 30? this is geometry

nirvana33 [79]

So the definition of the cosine of an angle of a right triangle is $\frac{adjacent}{hypotenuse}$ . You may remember this by SohCahToa (sine is opposite over hypotenuse, cosine is adjacent over hypotenuse, tangent is opposite over adjacent).

Remember, adjacent refers to the side next to the angle in question, and the side can't also be the hypotenuse. The hypotenuse is that longest side and is opposite the right angle.

We have the cosine of 30°. We write

$\cos(30)= \frac{adj}{hyp} = \frac{ \sqrt{3}}{2}$

Ben needs to choose between three brands of shingles to use on roof. he knows he needs 89 bundles of shingles but each type of s

kolbaska11 [484]

Probably brand A because it weights the least amount so then you can get more shingles in one lift since it needs to be at the most 650 pounds per lift.
