Answer:
a = <u>76°</u>
b = <u>124°</u>
Step-by-step explanation:
Since the lines are parallel, we can prove that the smaller triangle's missing angle (shares a line with ∠b) is 56°.
180-56=124°
∠b=124°
Now to find Angle A:
180-56-48=
124-48=
76°
∠a=76°
Answer:
x cubed minus y cubed is equal to 504
Step-by-step explanation:
First we need to know what the values of x and y are. We can do this pretty easily, by just solving both equations for x, and equating them to each other:
With the first:
x + y = 10
x = 10 - y
And with the other
x - y = 6
x = 6 + y
Now that we have two definitions of x, we can say that the expressions are equal, and solve for y:
10 - y = 6 + y
10 - 6 = y + y
4 = 2y
y = 2
And now that we know what y is, we can find x:
x = 10 - y
x = 10 - 2
x = 8
So x is equal to eight. We can check our answer by plugging x into the other equation and seeing if we get the same value for y:
x - y = 6
8 - y = 6
-y = 6 - 8
-y = -2
y = 2
So we know we solved that correctly.
Now if we cube each number, eight cubed is equal to 512, and 2 cubed is equal to 8. If we subtract the latter from the former we get 504.
so x cubed minus y cubed is equal to 504
It's adding 3 and subtracting 2 every time.
This means the next two terms would be +3 and -2 since the last one was -2.
The next term = 4+3=7
The next next term = 7-2=5
Answer: C. opposite leg/adjacent leg
Step-by-step explanation: Tangents use opposite over the adjacent side of the angle. You can use "SOH CAH TOA" which can help you with tangents, cosines, and sines. SOH = sine, CAH = cosine, and TOA = tangent. O = Opposite leg, H = Hypotenuse, and A = Adjacent leg.
