<u>Let's take this problem step-by-step</u>:
<u>The ;unlabeled angle' adjacent to the 'outside angle of measure 78°'</u>
⇒ is on a straight line
⇒ sum of angle measure = 180 degrees
<u>Now we know:</u>
⇒ sum of all angles in a triangle ⇒ 180°
<u>Let's put that in equation form and solve:</u>
<u>Answer: 21°</u>
<u></u>
Hope that helps!

Answer:
(-21/24) - (-20/24) = -1/24
<em>Simplest Form of the Equation</em>
(-7/8) - (-5/6) = 0.04166666666
8x6= 48,
-7x6=-42
6x8= 48,
-5x8=40
(-42/48) - (-40/48)
Divide both sides by 2
(-21/24) - (-20/24) = -1/24
Answer:
16x^2 -8x +1
Step-by-step explanation:
The square of a binomial expands as ...
(a +b)^2 = a^2 +2ab +b^2
So, you need to look for a trinomial with first and last terms that are perfect squares and a middle term that is double the product of the roots of those terms.
This pattern matches ...
16x^2 -8x +1 = (4x -1)^2
