Answer:
29
Step-by-step explanation:
if it is a right triangle, one of the angles are already 90 degrees. by giving me another angle, 61, all I have to do is add the 61 and 90 then subtract it from 180. A triangle is half of a square, a squares angles add together to make 360 degrees. a triangle is half of a square, so the angles add up to 180. that is why we subtract 151 from 180. doing that gives us the answer of 29. the third angle must be 29 degrees
Answer:
669
Step-by-step explanation:
First, we put the values of the given point into the general equation, giving:
0 = m * -1 + b .......(1)
Now plug in the given value of m into equation (1), giving:
0 = 2 + b ........(2)
Solving equation (2), we find that b = -2.
Now we can write the required equation as:
y = -2x - 2
