Use what you already know to find a, b, and c.
Valentin [98]

Answer:

Use the "find vertically opposite angle" method.

a = 80°

To find the other angles:

Since the angles equal up to 360 which makes a full circle shape...

360 - 80 - 80 = 200 (B and C)

200 ÷ 2 = 100 (Angle for B and C since they are vertically opposite, hence having the same angle)

b = 100°

c = 100°

What two numbers would make:<br> a + b = -11<br> AND<br> a x b = 28
ycow [4]

The first step I would do would be to list the factors of 28.

28(1)

14(2)

7(4)

Now notice that 7 + 4 = 11

So that means that -7 + -4 = -11.

Therefore, -7(-4) = 28

Your two numbers are - 7 and - 4.  Hope that helps!

Simplify: x0 y-3 / x2 y-1
svetlana [45]

\frac{x {}^{0}y {}^{ - 3}  }{x {}^{2}y {}^{ - 1}  }  \\  =  \frac{1y {}^{ - 3} }{ {x}^{2}y {}^{ - 1}  }  \\  =  \frac{1 \times 1}{ {x}^{2} y {}^{2} }  \\    \\  =  \frac{1}{ {x}^{2}y {}^{2}  }

Step by Step Explanation:

  • Evaluate the power: Any non-zero expression raised to the power of 0 equals 1
  • Simplify: Simplify the expression
  • Calculate the product: Any expression multiplied by 1 remains the same.

Which set of values could be the side lengths of a 30-60-90 triangle?
jeyben [28]
If we say that side "a" is the shortest (adjacent), side "b" is the second shortest (opposite), and side "c" is the longest (hypotenuse): then angle A would be 30°,  angle B would be 60°, and angle C would be 90°

tan B = b/a
 or
a tan B = b

they have 4 as the smallest value in all four options, so we know that a=4

4 tan 60° = b
tan 60° = √3
so, 4 tan 60° = 4√3
b=4√3

that leaves two options left, so now we find "c":

c^2 = (a^2) + (b^2)
OR
c= \sqrt{a^{2} + b^{2}}

c= \sqrt{4^{2}+(4\sqrt{3})^{2}}

c= \sqrt{16+48} \\ c=\sqrt{64} \\ c=8

so a=4, b=4√3, and c=8

Making your answer B
