Answer:
x = 7; y = 4 1/3
Step-by-step explanation:
The solution is the point of intersection of the lines.
Read the point of intersection.
You can also solve the system using algebra.
y = 1/3 x + 2
y = 4/3 x - 5
1/3 x + 2 = 4/3 x - 5
x + 6 = 4x - 15
-3x = -21
x = 7
y = 1/3 x + 2
y = 1/3 × 7 + 2
y = 2 1/3 + 2
y = 4 1/3
Answer: x = 7; y = 4 1/3
Answer: 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
