Answer: The scale factor is 3:1 because if you look at the T Point to T', it has a space of 3. Pardon for any mistakes. Good Luck!
Step-by-step explanation:
23. because there is a 90 degree angle and then the 67 degree angle, and triangle law says that all angles add up to 180.
You start off with 4*(cos(x+(pi/3)))
Let's place the 4 aside for the time being:
Cos(u+j) = cos(u)*cos(j) - sin(u)*sin(j)
cos(x+(pi/3)) = cos(x)*cos(pi/3) - sin(x)*sin(pi/3)
cos(x+(pi/3)) = cos(x)/2 - (sqrt(3)/2)*sin(x)
Multiplying by the 4 we put aside:
4*cos(x+(pi/3)) = 2*cos(x) - 2*sqrt(3)*sin(x)
The correct answer is B
Answer:
X = 0.87
Step-by-step explanation:
BODMAS
B - Bracket, O - Of, D - Division, M - Multiplication, A - Addition, S - Subtraction
Multiplication comes before addition and subtraction in the order, so
75X - 62 + 9 = 12
75X - 53 = 12
Add 53 to both sides
75X -53 + 53 = 12 + 53
75X = 65
Divide both sides by 75
X = 0.87
