Answer:
∠A ≈ 71.57
Step-by-step explanation:
<em><u>You use inverse tangent since it gives you the opposite and adjacent sides: </u></em>
≈ 71.565
<em><u>Round to nearest hundredth:</u></em>
≈ 71.57
Answer:
12 units
Step-by-step explanation:
Given that we are working with an equilateral triangle, we know that all sides are an equal length.
If one side measures to -2x + 8
and the other measures 3x -2
these expressions must equate to each other.
-2x + 8 = 3x - 2
Let's solve for x
-2x + 8 = 3x - 2 Add 2x to both sides
8 = 5x - 2 Add 2 to both sides to combine like terms
10 = 5x Divide both sides by 5 to isolate x
2 = x
Plug 2 in for x in either given expression
3(2) - 2 = 4
Each side of the triangle measures to 4
Since all 3 sides are the same length, we can simply multiply 4 by 3 to obtain our perimeter
4 * 3 = 12
I adore combining like terms! :)
First, let's combine x's:
2x-2x cancel out to 0
Now y's:
-4y
And now numbers or constants:
-4-6=-10
Now write all the terms together:
-4y-10
Hope it helps!

Hint: Draw a vector (arrow) from the origin to Point X. Now rotate that vector 180 degrees counterclockwise. Label the point at the end of this new vector X'.
Do the same for Poins Y and Z. Summarize what you have done, and choose the correct graph as your answer.
