U can use the Pythagorean theorem which is (a^2 + b^2 = c^2) It'll help you a lot
Enough force to push 135 pounds
Answer:
A) 5x-7y=58
B) y=-x+2 we rearrange B) into
B) x + y = 2 then we multiply B) by -5
B) -5x -5y = -10 adding this to A)
A) 5x -7y = 58 we get
-12y = 48
y = -4
B) x + y = 2
x = 2 +4
x = 6
Step-by-step explanation:
Answer:
if sin (x-3) degrees = cos (2x+6) degrees, find the value of x.
----------
Note: sin and cos are complementary functions....
sin(x) = cos (90-x)
-------------------
Your Problem:
sin(x-3) = cos(90-(x-3))
Equation:
90-[x-3] = 2x+6
90-x+3 = 2x+6
3x = 93-6
x = 31-2
x = 29
