Answer:
A) 3.44 ft²
Step-by-step explanation:
before cutouts, the area was 4 x 4 = 16 ft²
the circles have a diameter of 2 ft each, and a radius of 1 ft
each circle has an area pf (3.14)(1²) = 3.14 ft²
3.14 x 4 = 12.56 ft²
16 - 12.56 = 3.44 ft² left
Answer:
1= 70
2= 65
3= 95
For 1, just solve 180-(65+45) and then for 2, subtract #1 and 45 from 180. Then just solve for #3 by using 180-(#2+20)
It is PKO AND MKN because they are similar
Answer: x=25.6
Step-by-step explanation:Look at pic to see how it is solved.
Times 6.4 on both sides which gives you 25.6 .
Draw out and you'll see if make a triangle. Use Pythagorean theorem
you are given c and the other side
So,
c2 = a2 + b2
20^2 = 12^2 + b2
400 = 144 +b2
256 = b2
b = 16
Hope this helps
