It should be nine do you need to show work cause that's kinda hard to put it in words
A triangle can only equal 180 so you take 180-50 and get 130 then you divide 130 by 2 your answer is 65 X =65
If you had the hypotenuse and one of the legs you could subtract the to using Pythagorean theorem. you cant answer the question unless you have another leg or a degree or a right triangle. <span />
Let's start with y = 4x + b (since 4 is the slope);
We need to find what number should be put instead of b;
Then, let's see what needs to be done;
Plug in the y and x values from the coordinate (22,12) into y=4x+b;
12 = 4(22) + b
Solve;
12 = 88 + b
12 - 88 = b
b = -76
Remember the equation y = 4x + b? Put the -76 instead of b:
y = 4x + -76
or: y = 4x - 76
That is the equation.
To make it standard form, put x and y both in the left side, with x first then y:
-4x + y = -76
