Answer:
The answer is 1st point, 1/2×22.0×23.1
Step-by-step explanation:
You can let XY be the base and XZ be the height of the triangle. Then, by using the formula of the area of triangle, A=1/2×base×height to find the expression.

The third side must be >2 and < 18
To test if a triangle is acute, right or obtuse:
1) Square all 3 sides
2) Sum the squares of the 2 shortest sides
3) Compare this sum to side 3 squared
if sum > side 3 squared it is an acute triangle
if sum = side 3 squared it is a right triangle
if sum < side 3 squared it is an obtuse triangle
The shortest side 2 can be is "less than 2" so we'll say it is 2.00000001
three sides squared = 
<span>
<span>
<span>
4.00000004
</span>
</span>
</span>
64 
100
Summing the 2 shortest sides 4.00000004 + 64 = <span>68.00000004
</span><span>68.00000004 is less than 100 so it is an obtuse triangle no matter how long the third side is.

Step-by-step explanation:
The x intercept is the point that touches the x axis
The y-intercept is the point that touches the y-axis
So...
The x-intercept = (0, -40)
The y-intercept = (0, 15)
