Answer:

71

Step-by-step explanation:

This is the answer because:

1) First, add Andy's score and Janet's score in order to know how much they got in total:

  • Janet's score: 119 + 96 + 145 = 360
  • Andy's score: 127 + 74 + 88 = 289

2) In order to find how much more Janet scored, jus subtract Andy's score from Janet's score:

  • 360 - 289 = 71

Therefore, the answer is 71.

Hope this helps! :)

I don't know how to solve this
sergiy2304 [10]
The answer that I got was side  WX = 12 inches

It says that WY is congruent to XY which means that they are the same. That means that XY is also 3m-4. It also says that the perimeter of the triangle is 76 inches.

With this information I set up an equation:

3m-4 + 3m-4 +m = 76

(The number on the right side is the perimeter given to us in the problem and the numbers on the left side are the 3 side lengths).

I combined like terms on the left side and ended up with:

7m-8=76 

I added 8 to both sides of the equation and got 7m=84.

Finally I divided both sides by 7 and got m=12

m is equivalent to side WX..

Hope this helps!

HELP ASAP THIS IS GEOMETRY
tekilochka [14]

Answer:

x=48

y=70

step by step explanation:

In the question,

<em>Si</em><em>nce</em><em> </em><em>the</em><em> </em><em>trian</em><em>gle</em><em> </em><em>two</em><em> </em><em>sides</em><em> of</em><em> the</em><em> </em><em>traingl</em><em>e</em><em> </em><em>is</em><em> </em><em>equal</em><em>,</em><em> </em><em>it</em><em> </em><em>is</em><em> </em><em>an</em><em> </em><em>isosc</em><em>eles</em><em> </em><em>triangle</em><em>.</em>

<em>For</em><em> </em><em>an</em><em> </em><em>isosc</em><em>eles</em><em> triangle</em><em>,</em><em> </em><em>angles </em><em>oppos</em><em>ite</em><em> </em><em>to</em><em> </em><em>eq</em><em>ual</em><em> </em><em>sides</em><em> </em><em>are</em><em> </em><em>equal</em><em>,</em>

<em>Hence</em><em>,</em>

(x + 7) = 55

x = 55 - 7

x = 48

y = 180 - (55 + 55)

y = 180- 110

y = 70
