Marcus is drawing a triangle. He has used angle measures of 53.5 and 61º What angle measure will complete the triangle?
spin [16.1K]

Answer:

65.5 degrees

Step-by-step explanation:

Triangles add up to 180 degrees. So, the last value has to make the rest add up to 180.

Let x be the unknown degree.

61 + 53.5 + x = 180.

You cancel out the 61 and the 53.3 by subtraction, making you get

x = 65.5

Hope I helped !!! :)

Find the zeros of 7=x^2-8x-3 by completing the square
enot [183]

Using the completing the square method, for the equation, we have the zeros as <u>x = √26 + 4 and x = 4 - √26</u>

<h3>How can the zeros be found using completing the square method?</h3>

The given equation is presented as follows

7 = \mathbf{ {x}^{2}  - 8x - 3}

Which, by completing the square, gives;

{x}^{2}  - 8x - 3 - 7 = 0

{x}^{2}  - 8x - 10 = 0

{x}^{2}  - 8x  +   {\left(\frac{8}{2} \right) }^{2} - 10  -  {\left(\frac{8}{2} \right) }^{2} = 0

\mathbf{{(x - 4)}^{2} }   =26

The zeros of the equation;

7 =  {x}^{2}  - 8x - 3

are;

\underline{x = \pm \sqrt{26}  + 4}

(PLEASE! I NEED HELP! ASAP)
belka [17]

Answer:

74.4°F?

Step-by-step explanation:

It started at 65°F and they recorded the change. So 65 + 2.5 = 67.5 - 1.7 = 65.8 + 5.5 = 71.3 + 3.1 + 74.4? I think that is how it is solved. I could be wrong... it's been a while haha

^^That is finding the full temp. overall. If you are looking for the change, it is 9.4
