Given a triangle with the measure of the first angle is 7x, the measure of the second angle is

(x + 6) and the measure of the third angle is (2x + 4), find the measures in degrees of all three angles.

A triangle's angles sum to 180 degrees.

7x + x + 6 + 2x + 4 = 180

10x + 10 = 180

10x = 170

x = 17

1st angle = 7(17) = 119

2nd angle = 17 + 6 = 23

3rd angle = 2(17) + 4 = 38

Good question.

Anyway, you know that within any triangle, all of the interior angles equals 180 degrees.

The question gives you the three interior angles.

that means, 7x+(x+6)+(2x+4) = 180

simplifies to 10x+10 = 180

10x = 170

x = 17

Then we put this x value into the equations for each of the angles.

7(17) = 119

(17)+6 = 23

2(17)+4 = 38

Therefore, the three angles are 119, 23, 38.

7x+x+6+2x+4= 180 degrees (triangle)

combind the like terms

7x+x+2x= 10x 6+4= 1=

10x+10=180

subtract 10 from both sides

10x=170

divide 170 by 10

x=17

now you plug in

side 1= 7 times 17= 119

side 2= 17+6= 23

side 3= 17 times 2 +4= 38

Math 2 has a much extra suitable curve. attempt appearing some prepare tests. extraordinarily, the time-honored Math a million score is concerning to the comparable by way of fact the time-honored Math 2 score (by way of sizeable curve), so it appears that evidently so lots extra suitable to have that score for Math 2, do no longer you think of? maximum faculties settle for SAT Reasoning and venture attempt rankings till mid-January. Double verify with UC via calling or checking on line.
