Find the value of x HELP PLS

Ludmilka [50]

Answer:

x= 36

Step-by-step explanation:

both angles together are supplementary and will form 180

Therefore, you know the missing angle can be found by substracting 108 from 180

180 - 108 = 72

72 = 2x

Water boils at different temperatures at different elevations. The boiling temperature of water is 212 degrees * F sea level (0

Nikolay [14]

Answer:

The elevation when the boiling point of water is $190$ ° $F$ is 12790.70 feet

Step-by-step explanation:

Let every 1,000 feet of elevation be $x$ . Hence, we can write

$T = 212$ $- 1.72x$

Where $T$ is the boiling temperature of water at different elevations

Now, to the determine the elevation when the boiling point of water is $190$ ° $F$ .

We will determine $x$ by putting $T = 190$ ° $F$ .

Hence,

$T = 212$ $- 1.72x$

$190$ $= 212$ $- 1.72x$

$190 - 212$ $= - 1.72x$

$- 22$ $= - 1.72x$

$22 = 1.72x\\x = \frac{22}{1.72} \\x = 12.79070$

Since $x$ represents every 1,000 feet of elevation, then the elevation when the boiling point of water is $190$ ° $F$

$12.79070$ × $1000\\$ $= 12790.70$ feet

Hence, the elevation when the boiling point of water is $190$ ° $F$ is 12790.70 feet

The polygons are similar solve for x

Gnom [1K]

Answer:

x=12

Step-by-step explanation:

14/21=16/(x+12)

cross multiply

14(x+12)=16(21)

14x+168=336

14x=336-168

14x=168

x=12 (so the side would be x+12=24)

You could also see that 14 is 2/3 of 21, so 16 has to be 2/3 of x+12. That means x+12 would have to equal 24. If you take the 12 away from 24, x=12.

Analyze the diagram below and answer the question that follows. If <10 and <15 are congruent, which lines are parallel? A.

yanalaym [24]

If angle 10 and 15 are congruent ( the same) that would mean lines a and b would need to be parallel with each other because that have the same angles.

The answer ic C.
