There are a couple of sets of numbers that would add up to -294. Obviously -293 and -1, but I am sure your teacher wouldn't be to happy with that answer :D. A better answer could be -147 and -174; or maybe different numbers like -156 and -138.
I hope this helps!

Help you answer the questions, sure! Do the problems for you, nope.
in Problem 26 you have 2 small triangles. In the left one you have the angle 36 degrees, which means that the other acute angle is 90-36, or 54 (degrees). You'll need to find the height of the left triangle; finding that height is the same as determining the length of the side adjacent to the 36 degree angle.
Let that height be repr. by h.
Then tan 36 deg = h/21 Use the inverse tangent function to find the value of h.
Look at the triangle on the right. It has a 42 deg angle, and the length of the side next to it is h (which you found above). x is the hypotenuse.
Can you see that x*cos 42 deg = h? Knowing h, can you now find x?
If you have any qu. about this approach, please ask questions.
Answer:
coordinates of R(b,c)
slope of NM is 0.
Step-by-step explanation:
The midpoint of the line joining the points (x₁,y₁) and (x₂,y₂) is given by
The midpoint of the line segment NK is given by
∴R(b,c)
The slope of the line joining the points (x₁,y₁) and (x₂,y₂) is given by
Slope of RS is
Hence
coordinates of R(b,c)
and slope of NM is 0.
