Can someone tell me the answer to this please???

Answer:

Step-by-step explanation:

This is isosceles triangle

So, y = 53 {angles opposite to equal sides are equal}

53 + 53 + x = 180 {Angle sum property of triangle}

106 +x = 180

Subtract 106 from both sides

x = 180 - 106

x = 74

10. A cube has edge length c. (a) Write a formula for the surface area of the cube. (b) Use the formula to find the surface area

Anit [1.1K]

Answer:

a) $6c^2$

b) 216 cm^2

Step-by-step explanation:

A) the area of one face of the cube, is the side length x the side length. As it is a cube, all sides are the same length, so we do c x c = $c^2$

There are 6 faces in a cube so we have to times one face by 6 to get $6c^2$

B) c = 6

substituting this into the equation we made:

6 x (6)^2

6 x 36

216

So the surface area is 216 cm^2.

Hope this helps, let me know if you have any questions :)
