To find slope, use the equation (y2-y1)/(x2-x1). In your case, the equation is going to look like (-3 - -1)/(5 - -2) or (-3 +1)/(5 + 2), and that simplifies to -2/7.
Answer:
34=x
Step-by-step explanation:
180-68 =112 so angle PQS is 112 4x-3x is x so PSQ is x and now you can do x +x + 112 = 180 2x-68 x=34
I probably got it wrong tho, so sorry if it is incorrect
Cosine is
.
Apply the equation:
![sin(t) = \frac{3}{5} \\3^2 + b^2 = 5^2\\b^2 = 5^2 - 3^2\\\\\sqrt{b^2} = \sqrt{5^2}- \sqrt{3^2}\\\\\\b = 5 - 3 \\\\b = 2](https://tex.z-dn.net/?f=sin%28t%29%20%3D%20%5Cfrac%7B3%7D%7B5%7D%20%5C%5C3%5E2%20%2B%20b%5E2%20%3D%205%5E2%5C%5Cb%5E2%20%3D%205%5E2%20-%203%5E2%5C%5C%5C%5C%5Csqrt%7Bb%5E2%7D%20%20%3D%20%5Csqrt%7B5%5E2%7D-%20%5Csqrt%7B3%5E2%7D%5C%5C%5C%5C%5C%5Cb%20%3D%205%20-%203%20%5C%5C%5C%5Cb%20%3D%202)
B is the adjacent side so
cosine is:
Cos(t) = 5/2
Have a great day,
And I hope this helps you!
