Answer:
the triangle above is an isoceles triangle
therefore the base angles are equal
So we have:
X + X + 38= 180
2x = 180-38
2x = 142
X = 71°
The slope is m=5/4 and the y-intercept is b= -10
Show me a picture of the grid. (The square with the lines)
Ok it’s 1,345,234,324 is the answer
<h2><em>Width=w
</em></h2><h2><em>Length=l
</em></h2><h2><em>Perimeter=p
</em></h2><h2><em>
</em></h2><h2><em>p=2w+2l
</em></h2><h2><em>l=20+w
</em></h2><h2><em>p=2w+20+w+20+w
</em></h2><h2><em>p=4w+40
</em></h2><h2><em>
</em></h2><h2><em>4w+40=160
</em></h2><h2><em>4w=160-40=120
</em></h2><h2><em>w=120:4=30
</em></h2><h2><em>w=30
</em></h2><h2><em>l=20+w
</em></h2><h2><em>l=20+30=50</em></h2>
