<h3>Answer:  17</h3>

The more accurate value is roughly x = 16.5482258257411

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

Work Shown:

cos(angle) = adjacent/hypotenuse

cos(38) = x/21

21*cos(38) = x

x = 21*cos(38)

x = 16.5482258257411 which is approximate

x = 17

I'm rounding to the nearest whole number since the other side (21) is a whole number. If your teacher instructs you to round otherwise, then follow those instructions of course. Make sure your calculator is in degree mode.

Please help, Thanks
NeTakaya

Answer:

Step-by-step explanation:

There are two. This can be factored which will find both of them.

y = (x - 3)(x - 1)

x - 3 = 0

x - 3 + 3 = 3

x - 1 = 0

x - 1 + 1 = 1

x = 1

The zeros are (3,0) and (1,0)

A point that has a positive x-coordinate and a positive y-coordinate is located in which quadrant?
zhuklara [117]
Quadrant I or QI

This is tough to explain but here I go
If x and y is positive, it's QI
If x is negative and y is positive it's QII
If x and y are negative, it's QIII
If x is positive and y is negative It's QIV

So the answer is C
