Answer:length of side a is 42

Step-by-step explanation:

The given triangle ABC is shown in the attached photo. The length of side BC is a. The length of side AC is b and the length of side AB is c = 100

The sum of the angles in a triangle is 180 degrees. Therefore.

Angle A + angle B + angle C = 180. Therefore,

20 + 35 + angle C = 180

55 + angle C = 180

Angle C = 180 - 55 = 125 degrees. To determine the length if a, we would apply the sine rule which is expressed as

a/SinA = b/SinB = c/SinC

Therefore,

a/Sin20 = 100/Sin125

aSin125 = 100sin20

a × 0.8192 = 0.342 × 100

0.8192a = 34.2

a = 34.2/0.8192

a = 41.75

Approximately 42

I need help with answering the following questions. :/ :)
s344n2d4d5 [400]

Answer:

  a) (0, ∞)

  b) (-∞, ∞)

  c) x = 0

Step-by-step explanation:

It helps to have some idea what the log function is.

__

a) The domain is all positive numbers: (0, ∞).

b) The range is all real numbers: (-∞, ∞). (The vertical translation downward by 5 units does not change that.)

c) There is a vertical asymptote where the argument of the log function is zero: at x=0.

the diameter of a cylindrical construction pipe is 4 ft. if the pipe is 19 ft long, what s it’s volume?
STALIN [3.7K]

Answer:

76\pi or 238.76 units^{3}

Step-by-step explanation:

The volume of a cylinder is V = \pi r^{2} h

Here the radius is  r = \frac{1}{2} d = \frac{1}{2}(4)=2

The height is given as 19 ft

Then plug in all the numbers into the equation

V = \pi (2^{2})(19) = 76\pi = 238.76 units^{3}
