So you know that all the angles in a triangle must add up to 180. Therefore, you can make this equation:
[tex](-20x+3)+(-40x+18)+(-15x+9)=180[/tex]
And now just solve for x!
[tex]-75x+30=180\\-75x=160\\x=\frac{160}{-75}\\x=-2.4[/tex]
So, your answer is:
x = -2.4
X = -2.4

Answers
Answer:
y = x + -2.3
x = -y - 2.3 (but why would one need this?...)
Step-by-step explanation:
(6.1 - (-9.7))/(8.4 - (-7.4)) = 15.8/15.8 = 1
6.1 = 8.4 + b
b = -2.3

The relation between angle DCF and CFG is co-interior angles, or same side interior angles.
Angle(DCG+CFG)=180
Measure of DCF=180-3x=147 [Because Angle DCF+ACD=180, Angles in a straight line]
Measure of CFG=180-6x-81=33 [Because AngleCFG+HFG=180, Angles in a straight line]

find three consecutive even integers whose sum 72
Answers
22, 24, 26
Step-by-step explanation:
2n - 2 + 2n + 2n + 2 = 72
6n = 72
n = 72/6
n = 12
∴ so three consecutive even integers whose sum is 72 :
2n - 2
= 2(12) - 2
= 24 - 2
= 22
2n
= 2(12)
= 24
2n + 2
= 2(12) + 2
= 24 + 2
= 26
verification
22 + 24 + 26
= 46 + 26
= 72 ✓✓
