Answer:

x = 71°

Step-by-step explanation:

because the triangle shown in the image is an isosceles if the top angle is 38 the sum of other two angles must be 142 which is ,if divided by 2, makes 71

Answer:

X = 71°

Step-by-step explanation:

Fierst of all that's an isosceles Triangle.

Isosceles triangle are triangles that have two sides and two angles equal .

To determine mine x, we are given one angle to be 38°.

Total angle in a triangle= 180

In that triangle

X+X+38= 180

The other angle is equal to X .

2X = 180-38

2X = 142

X =142/2

X = 71°

Find the surface area of the figure below.
gayaneshka [121]

Answer:

261 cm²

Step-by-step explanation:

To find the surface area of a square pyramid, you must first recognize all of the shapes.

There are four triangles and one square.

  • To find the area of a square, multiply the side by itself twice.
  • To find the area of a triangle, multiply the base and the height, then multiply the product by 1/2.

The triangles have a base of 9 and a height of 10.

9*10=90

Multiply the product by 1/2.

90*1/2 = 45

There are four triangles.

45*4=180

The area of all three triangles is 180 centimeters; the area of a single triangle is 45 centimeters.

There square has sides of 9 centimeters.

9*9=81

The area of the square is 81 centimeters.

Lastly, we add the areas of the shapes.

45+45+45+45+81 = 261.

Therefore, the surface area of this square prism is 261 cm².

You can use this layout to find the surface area of a square pyramid.
