If tan x° = 3 divided by y and cos x° = y divided by z ,what is the value of sin x°?
DedPeter [7]
Given:
tan x = 3/y
cos x = y/z

Because tan x = sin(x)/cos(x), therefore
sin x = tan(x)*cos(x)
         = (3/y)*(y/z)
         = 3/z

Answer: a) sin x = 3/z

I need to find the value of x and the measure of the exterior angle
adell [148]

Given:

In a right angle triangle, the measure of exterior angle is (9x+16)^\circ.

The measure of opposite interior angle is (5x-14)^\circ.

To find:

The value of x.

Solution:

Exterior angle theorem: In a triangle the measure of an exterior angle is equal to the measure of sum of two interior angles.

Using exterior angle theorem, we get

(9x+16)^\circ=90^\circ+(5x-14)^\circ

(9x+16)^\circ=(5x+76)^\circ

9x+16=5x+76

Isolate the variable x.

9x-5x=-16+76

4x=60

x=\dfrac{60}{4}

x=15

The value of x is 15. So, the measure of the exterior angle is:

(9x+16)^\circ=(9(15)+16)^\circ

(9x+16)^\circ=(135+16)^\circ

(9x+16)^\circ=151^\circ

Therefore, the value of x is 15 and the measure of the exterior angle is 151 degrees.

Degree of the polynomial (2x^3)-(x^2+11) .
WARRIOR [948]

First, distribute the terms.

1(2x^3) = 2x^3

-1(x^2+11) = -x^2-11

Standard form:

2x^3 - x^2 - 11

Since there is a 3, the degree of polynomial is cubic.
