Answer:

86.33 square micrometers

Step-by-step explanation:

A silicon wafer is textured to minimize light reflection. This results in a surface made up of square pyramids. Each triangular face of one of the pyramids has a base of 5 micrometers and a height of 5.6 micrometers. Find the surface area of the pyramid, including the base.

The formula for the Surface Ares mma is given as :

A=a² + 2a √a²/4+ h²

a = base edge = 5 micro meters

h = height = 5.6 micro meters

=5²+2× 5 × √5²/4+ 5.6²

= 86.32699 square micrometers

≈ 86.33 square micrometers

2x  -  48  =  10x

-2x                -2x

-48  =   8x

/8          /8

-6   =  x

if you move all of your x's on to the same side it is easier to solve

If m ACB = 48° and <br> m CAB = 47°, is line BC a tangent to circle A?
muminat

Answer: No, because ABC is not a right angle.


Step-by-step explanation: In triangle ABC, the three angles add up to 180

So angle B = 180 - 48 - 47 = 85.
