Answer:

78 degrees

Step-by-step explanation:

If you look at it, 2 of the angels are the same- those angels are A and B- the angel we are looking for. Angel A is 78 degrees and if angel A and angel B are equal then angel B is also 78 degrees.

Write an equation of the line that passes through (2,5) and is parallel to the line 2y = 3x + 10.

Advocard [28]

Answer:

y = 3/2x - 8 hope I helped

Step-by-step explanation:

To find the equation of a line, we need a point and a slope. We're given a point, and we can easily get the slope. First let's solve 2y = 3x + 10 for y so we can get the slope (recall that y = mx + b is the slope-intercept form, and m is your slope).

2y = 3x + 10 --> almost there already, just divide everything by 2 to get y by itself.

y = 3/2x + 5 --> now you have it in the y=mx + b form, so your slope is 3/2

They asked for the parallel line, remember parallel lines have the same slope, therefore you use the same slope.

Now we know that our slope is m = 3/2 and our point is (2, -5)

You can always find the equation of a line using the Point-Slope Formula:

y - y1 = m(x - x1) --> our x1 is 2 and our y1 is -5, and slope is 3/2

y - (-5) = 3/2(x - 2) --> Be careful when you have minus a negative number, like we do here. It becomes:

y + 5 = 3/2(x - 2) --> now distribute the 3/2

y + 5 = 3/2x - 6/2

y + 5 = 3/2x - 3 --> now we can subtract 5 from both sides to get it into slope intercept form.

y = 3/2x - 8 --> This is the equation of a line that is parallel to 2y=3x+10 & passes through (2, -5)

Please someone help please pls

Answer:

h= $h= \frac{5R^{3} }{LU}$

Step-by-step explanation:

1.) You must isolate the h from the equation by dividing both sides by L (or multiply by its reciprocal, which in this case, the reciprocal on L is $\frac{1}{L}$ .....So it would look like:
