Answer:
Sin Z = 8/17
Tan G = 15/8
Cos Z = 15/17
Sin M = 1
Step-by-step explanation:
Sin is equivalent to Opposite over Hypotenuse. For Z, the opposite would be 40. 85 is always the hypotenuse in this problem.
Sin Z = 40/85, simplified it is 8/17
Tan is opposite over adjacent. In this case, the opposite is 75. The adjacent is 40.
Tan G = 75/40, simplified it is 15/8
Cos is adjacent over hypotenuse. In this one, the adjacent is 75. The hypotenuse is 85.
Cos Z = 75/85, simplified it is 15/17.
In Reference to what I said above Sin, I will use the same thing.
Sin M = 1
85/85
because y^3 is raised to the power of two, we will have to multiply the exponents rather than adding them.
By distributing the power of 2, we will get y^2(6).
Because now the exponents are being multiplied, we can just add them to get y^8. The other y has a power of 1, so we'll just add the power of that y as well to get y^9.
summary:
multiply exponents if they are being raised to a power.
add exponents if they are being multiplied, and only add them if they have the same base (in this case, both the bases of the exponents are y, so we can add them)
Answer:
18
Step-by-step explanation:
-11 - 7 = -18
|-18| = 18
Answer:
300pi
Step-by-step explanation:
that is 3/4 of a circle with the radius of 20. Meaning that the area is 300pi
Answer:
28 = x
Step-by-step explanation:
62 = angle BAC since they are vertical angles
angle ABC is a right angle since KL is perpendicular to FG
Adding the angles in triangle ABC
BAC + ABC + BCA = 180
62 + 90 + BCA = 180
152 + BCA = 180
BCA = 180-152
BCA = 28
BCA = x since they are vertical angles
28 = x
