Answer:
m∠a = 60°
Step-by-step explanation:
Hi there,
Before answering this question, you should know that the sum of all the angles in a triangle will always be 180°. Therefore, we can write this equation to find the value of ∠a :
70° + 50° + m∠a = 180°
Solve for m∠a
120° + m∠a = 180°
m∠a = 60°
Hope this answer helps. Cheers.
1/4 = 0.25
s0 3 1/4 = 3.25
62x3.25 = 201.50 miles = 201 1/2 if you need it in fraction form
If it doesn't matter whether the points are integers or not you can just pick a number for either y or x and solve for the other variable. For example, if you pick 3 to be your x, plug it in and then solve for y. Start out with:
![7x-3y=42](https://tex.z-dn.net/?f=7x-3y%3D42)
Plug in 3 for x:
![7(3)-3y=42](https://tex.z-dn.net/?f=7%283%29-3y%3D42)
. Then,
![21-3y=42](https://tex.z-dn.net/?f=21-3y%3D42)
. Subtract 21 from both sides and then divide by -3 on both sides. You end up with y=-7 so one of your points is (3, -7)
