Answer:
12.3
Step-by-step explanation:
You will use cosine to solve for y because you are given the hypontenuse and need to find the adjacent side.
cos 35 degrees = adjacent/hypontenuse
cos 35 = y/ 15
15( cos35 ) = y
y=12.287
=12.3
Some numbers you must know automatically know, so my suggestion is either search up the number or if you divided keep it with the division as a fraction.
48÷8=6, 8×6=48, 48<span>÷6=8</span>
Answer:
y=-2x+7
Step-by-step explanation:
The formula for this is y=mx+b
the m is the slope, and the b is the intercept, just plug them both in to make it work.
