Answer:
B
Step-by-step explanation:
Let's create an equation in point-slope form, which is: , where
is the point and m is the slope.
Here, our point is (-2, 7) and our slope is m = -5 so plug these in:
Now, if (a, 2) lies on this line, then it should satisfy the equation. So plug in a for x and 2 for y:
2 - 7 = -5(a + 2)
-5 = -5(a + 2)
Divide by -5:
1 = a + 2
Subtract 2 from both sides:
a = -1
Thus, the answer is B.
Hope this helps!
<em>In decimal form, a = 114.5; b = 25.5</em>
We will write this as a system of equations, where and
are the two angles.
We will use substitution to solve this system. We know what equals, so we plug that into the second equation.
Combine the like terms.
Add on both sides.
Divide both sides by .
Now just subtract that from .
