Answer:
x = 49°
Step-by-step explanation:
The sine of an angle is equal to the cosine of its complement:
x = 90° -41° = 49°
Can you take a picture of the problem?
Answer:
x=-3
Step-by-step explanation:
(4)(2) + 4x = -4
multiply the 4 and 2
8 + 4x = -4
subtract 8 from both sides
4x = -12
divide both sides by 4
x = -3
Simple, since you want to find y, in y=mx+b form, move everything to the other side.
1/2x-y=4
Move 1/2x
1/2x-y=4
-1/2x -1/2x
Making it look like,
-y=4-1/2x
Divide by the negative 1 in front of the y,
-y=4-1/2x
/-1 /-1
y=-4+1/2x
or
y=1/2x-4
Thus, this written in y=mx+b form, y=1/2x-4.
