Error Analysis: A student solves the equation S=2Lw+2Lh+2Wh for W and his answer are W=S-2Lh-2Lh\h Describing and correct the st
serious [3.7K]
S=2LW+2LH+2WH

First, subtract 2LH from both sides
S-2LH=2LW+2LH-2LH+2WH
S-2LH=2LW+2WH

Separate out the W
S-2LH=W(2L+2H)

Divide by 2L+2H to get W alone

\frac{S-2LH}{2L+2H} =W

Hope this helps.

In triangle WXY , angle X cong angle W YW = 19 and WX = 15 15. Find the length of XY.
ivolga24 [154]

Answer:

<h3>19</h3>

Step-by-step explanation:

Given the triangle WXY, with angle X and W to be equal, this shows that the triangle is an isosceles triangle. An isosceles triangle is the one which has two of its sides and its base angle to be the same.

If <X = <W, then The sides YW = XY

That is the other two sides asides from the side XW are equal.

Since YW = 19

Hence the measure of the side XY will also be 19

YW = XY = 19
