Hello!
All the angles inside a triangle is equal to 180
To find x you can do
180 - 50 - 70 = 60
x = 60
To find y you have to find the other missing angle in the other triangle
180 - 50 - 60 = 70
A line is equal to 180°
To find y you do
180 - 60 - 70 = 50
x = 60 and y = 50
Hope this helps!
Given:
Length of a cube is 2 cm
To Find:
Surface area of the cube
Solution:
A cube consists of 6 faces.
The area of each face = side x side
So, the total surface area of a cube = 6 x
side x side
Let a be the length of the given cube
: Surface area of a cube = 6a square
a = 2 cm (Given)
Surface area of cube = 6 x 22 =(6 x 4) = 24 cm square.
Hence, the surface area of the given
cube is 24cm square.
Hope it helps!
