The solution will be (7,-5), so the y-value is -5 $${y=3x-26 \atop y=2x-19}$

We can subtract y=2x-19 from the top, resulting in 0=x-7, or x=7.

If we then put x=7 into the top formula, we get:

y=3(7)-26

y=21-26

y=-5$

What is the area of this triangle?

tigry1 [53]

Answer:
Area = 48.6 in²

Explanation:
The area of the triangle can be calculated using the side-angle-side method as follows:
Area = 0.5 * first side * second side * sin(angle included between the two sides)

This rule is illustrated in the attached image.

Now, we have:
first side = 13 in
second side = 7.5 in
The angle included between the two sides = 94 degrees

The given angle is included between the two given sides, therefore, we can apply the above rule to get the area.

Area of triangle = 0.5 * 13 * 7.5 * sin(94)
Area of triangle = 48.63 which is approximately 48.6 in²

Hope this helps :)
