In triangle △WXY, XY ≅ WX and m∠X=38 Find m∠W
allsm [11]

Answer:

71^{\circ}

Step-by-step explanation:

Since two sides of the triangle are equal in length, we can conclude that \triangle WXY is an isosceles triangle. With this information, we can draw an isosceles triangle to find m\angle W. Since the base angles of an isosceles triangle are equal, we can solve for m\angle W:

38 + m\angle W + m\angle Y = 180 (Angle sum of triangle is 180^{\circ})

38+2(m\angle W) = 180 (Base angles of isosceles triangles are equal, there is an image attached to show that m\angle W is one of the base angles)

2(m\angle W) = 142

m\angle W=71^{\circ}

Hope this helps :)

Lapatulllka [165]

The real distance fro the shop to the store is 24 km

<em><u>Solution:</u></em>

Given that, Jakes map shows the distance from the bake stars cafe to the restaurant supply store as 3 centimeter

Scale of the map is 1 centimeter to 8 kilometers

Therefore, scale is:

1\ centimeter : 8\ kilometer

Let "x" be the real distance from the shop to the store

Then by proportion, we get,

\frac{1\ centimeter}{8\ kilometer} = \frac{3\ centimeter}{x\ kilometer}\\\\\frac{1}{8} = \frac{3}{x}\\\\x = 3 \times 8\\\\x = 24

Thus real distance fro the shop to the store is 24 km

1 QUESTION-30 POINTS<br> QUESTION PINNED BELOW
galina1969 [7]

Answer:

The scale is not reasonable.

Step-by-step explanation:

The painting is 48 inches  by 120 inches

The scale is 1 inch = 4 inches

Divide the painting size by 4

48/4 = 12 inches

120/4 = 30 inches

We would need paper that is

12 inches by 30 inches

Our paper is 12 inches by 24 inches

It is too small.  The scale is not reasonable
