Answer:

let the measure of other angle be x,then,

X+46=90

X=90-46

X=44

therefore the measure of other angle is 44 degree

Question in picture ​
tresset_1 [31]

Answers:

cos(A) = 0.8480

tan(B) = 1.6

=============================================

Explanation:

Before we can compute cos(A), we'll need to find the hypotenuse.

Use the pythagorean theorem.

a^2 + b^2 = c^2

8^2 + 5^2 = c^2

89 = c^2

c^2 = 89

c = sqrt(89)

The hypotenuse is exactly sqrt(89) units long.

This will allow us to find the cos(A) value

cos(angle) = adjacent/hypotenuse

cos(A) = AC/AB

cos(A) = 8/sqrt(89)

cos(A) = 0.84799830400509 which is approximate

cos(A) = 0.8480 when rounding to four decimal places

-------------------------

For the tangent ratio, we won't use the hypotenuse. Instead, we use the opposite and adjacent sides like so:

tan(angle) = opposite/adjacent

tan(B) = AC/BC

tan(B) = 8/5

tan(B) = 1.6

What is the exact volume of the cylinder?
suter [353]

Answer:

<h2>volume of the cylinder = 128πin³</h2>

Step-by-step explanation:

The question is incomplete. Here is the complete question;

'What is the exact volume of the cylinder? 32π in³ 64π in³ 128π in³ 512π in³ Cylinder with radius labeled 4 inches and height labeled 8 inches'

Volume of a cylinder = πr²h

r is the radius of the cylinder

h is the height

Given r = 4in

h = 8in

Volume =  π(4)²*8

volume of the cylinder = 16π*8

volume of the cylinder = 128πin³

Mnenie [13.5K]

Answer:

  D.  157°

Step-by-step explanation:

∠EFB and ∠AFB form a linear pair, so are supplementary.

∠EFB = 180° - ∠AFB = 180° -23°

∠EFB = 157°
