Examine the diagram. A triangle. Angle B is the exterior angle to angle A. The other 2 exterior angles are 100 degrees and 127 degrees. Follow these steps to apply what you have learned about the angles of a triangle. Find m∠B : 100° + 127° + m∠B = 360° Then, find the measure of angle A. Which is the measure of angle A? 133° 53° 47° 80°

hey um this isn't an answer but do you know the answer to this

Step-by-step explanation:

Arnold is planning on painting a mural. Before painting the mural, Arnold painted the picture on a paper that is 5 inches wide and 11 inches tall. Arnold is using a scale in which 1/2 inch represents 1 foot to paint the mural.

How tall will the actual mural be?

How wide will the actual mural be?

y = 3x+4

step-by-step explanation:

to find the slope

slope = (y2-y1)/ (x2-x1)

    = (-8-4)/ (-4-0)

    = -12/-4

  = 3

using the slope intercept form of a line

y= mx+b

we know the slope is 3

we know the y intercept is 4 ( the point where it crosses the y axis or x=0)

y = 3x+4

answer: 0.26
