A triangle has angle measures of 47 degrees and 92 degrees. What is the measure of the third angle?
ludmilkaskok [199]

Answer:

The missing angle is 41 degrees

Step-by-step explanation:

First of all, a triangle is measured at 180 degrees in total

To find the missing measurement for the third angle, add the 47 and 92 degrees together which would equal 139 degrees.

47+92=139 degrees

Next just subtract 139 from 180 to get your answer.

180-139=41 degrees

The answer is 41 degrees

Line L has equation y = 4x - 7, and line M is parallel to line L and passes through the point (2, 15). Determine the equation of
Artist 52 [7]

Answer:

A: y = 4x + 7

Step-by-step explanation:

Step 1:  Our line is parallel to this line, so it has the same slope, but a different  y-intercept, so set up the equation...

  y = 4x + b      

We are given a  point (x, y) of (2, 15), so plug that in and solve for b.  

 15 = 4(2) + b

    15 = 8 + b      (simplify)

        7 = b      (subtract 8 from both sides to isolate b)

So the equation of our line is  y = 4x + 7

ElenaW [278]
12 x^{4} * (- \frac{5}{6} x^{3} y^{2})
Now multiple the coefficients and add the exponents with common bases
12 * - \frac{5}{6} = -10 \\  x^{4} +  x^{3} =  x^{7}
Now write your final expression
-10 x^{7}  y^{3}
