The measures of the angles of a triangle are in the ratio of 2 : 5 : 8

a. find the measures of all three angles.
b. classify the triangle as acute, right, or obtuse.

The measures of all the three angles are 24 , 60 and 96

Step-by-step explanation:

Since the measures are given in ratio form, the first thing is to find the total ratio, which is

2 + 5+ 8 = 15

Recall that the sum of angles in a triangle is 180 ,so to calculate each angle , we have

2/15 x 180 = 24

also , 5/ 15 x 180 = 60

Finally, 8/15 x 180 = 96

The triangle is obtuse , since it is having one angle greater than 90.

It can not be acute because of the existence of 96 , for a triangle to be acute , all the angles must be less than 90 , and it can not be right triangle because there is no existence of 90

its definatley   this on your answer choice?

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
