Answer:
30 tons
Step-by-step explanation:
Consider only triangle BDH. Interior angles B and D are given, and "x" is the exterior angle at H. The measure of that exterior angle is the sum of the measures of the opposite interior angles (B, D).
x = ∠B +∠D
x = 46° +33° = 79°
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
Add 18 + 30 = 48, the most groups will be 24 with 2 flowers in each group! hope I helped
