Answer:

see consider there are three angle 80 and x and 45(the measure of line is 180 so subtract 180 by 125 u will get 45) now measure of angle is 180 soo the value of x is 55degree so value of x is equal to that of z therefore value of z also 55 degree

How do you do a 3-step algebra equation?

Vlad1618 [11]

The goal of all algebra equations is to isolate the variable. In 3 step you should first make sure both variables are on the same side. To do that make sure you use the inverse.
For example:
6a + 9 = 3a + 15
because 3a is positive you're going to want to subtract it.
6a + 6 = 3a + 15
-3a -3a
_______________
3a + 6 = 15

Now it's a 2 step equation and you solve it on from there.

Consider a triangle ABC for which ∠A=100∘,a=34,b=13. If such a triangle can not exist, then write NONE in each answer box. If th

bekas [8.4K]

Answer:

B is 22.12 degrees; ∠C is 57.88°; c=29.24

Step-by-step explanation:

So, first, it's important to draw a diagram of the triangle the problem is talking about (see attached picture).

Once the triangle has been drawn, we can visualize it better and determine what to do. So first, we are going to find what the value of angle B is by using law of sines:

$\frac{sin B}{b}=\frac{sin A}{a}$

which can be solved for angle B:

$sin B=b\frac{sin A}{a}$

$B= sin^{-1}(b\frac{sin A}{a})$

and substitute the values we already know:

$B= sin^{-1}(13\frac{sin 100 ^{o}}{34})$

which yields:

B=22.12°

Once we know what the angle of B is, we can now find the value of angle C by using the fact that the sum of the angles of any triangle is equal to 180°. So:

A+B+C=180°

When solving for C we get:

C=180°-A-B

C=180°-22.12°-|00°=57.88°

So once we know what angle C is, we can go ahead and find the length of side c by using the law of sines again:

$\frac{c}{sin C}=\frac{a}{sin A}$

and solve for c:

$c=sin C \frac{a}{sin A}$

so we can now substitute for the values we already know:

$c=sin(57.88^{o})\frac{34}{sin(100^{o})}$

which yields:

c=29.24

solmaris [256]

Answer:

79%

Step-by-step explanation:

fraction = 158/200

Denominator has to be over 100 to be able to be converted to percent

158/200 = 79/100

79/100 = 79%
