How do i write these out into equations?

1. The sum of the measures of three angles is 180. One measure is twice the size of the other two. Find the measure of each angle.

2. The sum of the measures of three angles is 180. One measure is half the size of the other two. Find the measure of each angle.

1. Let x, y & z represent the three angles.

x+y+z = 180

x = 2y; y = z

Substitute 2y for x and y for z & Solve:

2y + y + y = 180…

2. Let x, y & z represent the three angles.

x+y+z = 180

x = 0.5y

y = z

Substitute 0.5y for x and y for z & Solve:

0.5y + y + y = 180…

1. Let a, b and c the 3 angles.

a+b+c=180

a=2(b+c)

substitute a to the equation a+b+c=180

2(b+c)+b+c=180…

and so on…^^

2. Let a, b and c the 3 angles

a+b+c=180

a=(b+c)/2

substitute a to the equation a+b+c=180

(b+c)/2+b+c=180…

and so on^^

hope that helps…

1. 2x + x + x = 180

2. 1/2 x + x + x = 180
