Step-by-step explanation:
- The first reason is given. Since the question gave us those, we say its given.
- The second/third reason is also given
- The fourth reason is alt int angles. A transversal crosses through parallel lines AB and DE.
- The fifth is definition of a midpoint.
- The final is SAS
Answer:
x=177
Step-by-step explanation:
vertically opp angles are equal so 149=x-28, to find x you do 149 +28 whiichis 177
Answer:
45.24
Step-by-step explanation:
Percentage Calculator: 38 is what percent of 84? = 45.24.
Answer:
80π
Step-by-step explanation:
Circle O with radius IO:
large radius = IO = 12 = R
Circle O with diameter JK
IJ = JK = KL = 2 × IO = 24
IJ = JK = KL = 24/3 = 8
small radius = 8/2 = 4 = r
The shaded area is a semicircle of radius 12 minus a semicircle of radius 4 plus two semicircles of radius 4.
That is the same as
1 semicircle of radius 12 plus 1 semicircle of radius 4
A = πR²/2 + πr²/2
A = π(12² + 4²)/2
A = 160π/2
A = 80π
C. x = 9 bc if you calculate it all of than than you will get you answer :)
