Elanso [62]

Answer:

y=\frac{5}{6}x-2

Step-by-step explanation:

Using the formula rise/run I calculated the slope. Then I saw the line passes through the point in the y axis -2. So the equation would be y=5/6x-2

Answer:

C) ∠LMO = 50°

Step-by-step explanation:

When you add the degrees of all the angles in a triangle, you get 180, so...

180 = 60 + 70 + x

180 - 60 - 70 = x

x = 50

HELP THIS IS TRIGONOMETRY OR GEOMETRY!!!
Dmitry_Shevchenko [17]

Answer: PR=14.5.

Step-by-step explanation:

1. If the area of PQR is 50, then (QR*PQ)/2=50, so QR*PQ=100 (the area of a triangle is the base*height/2).

2, The tangent of an angle is (the opposite side)/(the adjacent side). So, the tangent of angle P=QR/PQ. Angle P is 36 degrees, and the tangent of 36 degrees is 0.726542528. We can substitute this into the equation we found to get 0.726542528=QR/PQ.

3. Using the equations we found in Steps 1 and 2, we can create a system of equations:

\left \{ {{QR*PQ=100} \atop {QR/PQ=0.726542528}} \right.

We can solve this system of equations to get PQ=11.7319 and QR=8.52375.

4. Using Pythagorean theorem, we can say that PR^2=QR^2+PQ^2. If we substitute the values of PQ and QR into the equation, we can come to the conclusion that PR=14.5014410206, which simplifies to PR=14.5.
