2 + 2 equals to 4
You can do it on the calculator too.
X would equal 60 degrees because the degree of the top left area is equal to the degree of the bottom right. So the equation would be x+20=80 so you would solve to get x=60
Answer:
75 degrees
Step-by-step explanation:
Use trigonometry
we are given opposite(27) and hypotenuse(28), so use sin
sin=opp/hyp
sin(x)=27/28
x=arcsin(27/28)
x=74.64111442
X/4+7=y
x being your "number" and y being the answer
Answer: X^2-x-1=y
Step-by-step explanation:
Multiply every number inside the parentheses
(X+3)(x-4)
X^2-4x+3x-1
Add all similar numbers and we get
X^2-X-1
