Switch sides
Abc=d
Now divide both sides by bc to get a .
A= d/bc
Answer: 119°
Step-by-step explanation:
The total of the interior angles of a triangle is 180° so if you add the two angles you have, you get 61 and just subtract that from 180 to get the missing angle.
Answer:
x = 3 and 1/3
Step-by-step explanation:
First, get the interior angle of the 114 by subtracting 114 from 180, and you should get 66. Next, add the two known interior angles of 66 and 64 to get 130. With the knowledge that the 3 interior of all triangles add up to 180, you should know that 3x-40 is equal to 180 -130, or 50. With 3x+40 = 50, start by subtracting 40 from both sides for 3x = 10. Finally, divide both sides by 3 to get x = 3 and 1/3
Answer:
The expression is not factorable

Answer: m = 2, b = 1</h3>
The y intercept is where the graph crosses the vertical y axis. In this case, it's at the point (0,-1). Focus on the y coordinate and we see y = -1. The y intercept is b = -1.
The slope is m = 2 because we start at a point like the y intercept, and do the following steps
- go up 2
- go over to the right 1
and arrive at the point (1,1) which is also on the graph. We can follow these steps again to go from (1,1) to (2,3) and so on.
Alternatively, you can pick two points on the graph such as (1,1) and (2,3) to use the slope formula
m = (y2 - y1)/(x2 - x1)
m = (3-1)/(2-1)
m = 2/1
m = 2
Either way, the slope is 2.
