Sum of the angles of triangle is 180° !!
and in this question, the sum is 80+80+40=200 °
Thus not any triangle can be formed ! so ANS is A ; none !!
Answer:
1. 3
2. 12
3. 27
Step-by-step explanation:
<span>y=1/5x+5 with the point (-6, 0)
The line perpendicular to this line will have a slope that's the negative reciprocal of this one. So if the slope here is 1/5 (based on y=mx+b, where m is the slope), then the perpendicular slope would be -5/1.
So now that you have the point and the slope, use the point-slope formula.
y - y</span>₁ = m(x - x₁)
m = -5
(x₁, y₁) = (-6, 0)
y - 0 = -5(x + 6)
y = -5x - 30
y = -5x - 30 is the line perpendicular to y=1/5x+5.
Answer:
![(-\infty,+\infty)](https://tex.z-dn.net/?f=%28-%5Cinfty%2C%2B%5Cinfty%29)
Step-by-step explanation:
The given inequality is 3x-2>4 or ![5x-3\leq 7](https://tex.z-dn.net/?f=5x-3%5Cleq%207)
We group similar terms to obtain: 3x>4+2 or ![5x\le7+3](https://tex.z-dn.net/?f=5x%5Cle7%2B3)
Simplify to get:
3x>6 or ![5x\le10](https://tex.z-dn.net/?f=5x%5Cle10)
x>2 or ![x\le 2](https://tex.z-dn.net/?f=x%5Cle%202)
This implies that the solution set is all real numbers.
The solution in interval notation is ![(-\infty,+\infty)](https://tex.z-dn.net/?f=%28-%5Cinfty%2C%2B%5Cinfty%29)
