Answer: 3,6,9,12,15
Step-by-step explanation:
Im not sure how to explain this but if you listen to school house rock multiple of three song it helps.
Answer:
The number of faces is 29
Step-by-step explanation:
we know that
The Euler's formula state that, the number of vertices, minus the number of edges, plus the number of faces, is equal to two
In this problem we have
Substitute in the formula and solve for F
Answer:
(a) ∠EFH = 68°
(b) ∠EGF = 21°
Step-by-step explanation:
(a) The given parameters are;
The diameter of the circle = Segment
Arc = 138°
∠GFH = 22°
∠ EFG = (Angle subtended by the diameter EG at the center)
Arc mEG = 180° (Arc subtended by the diameter of a circle = 180°)
∠ EFG is subtended by the diameter EG at the center
∴ ∠ EFG = 90° (Angle at the center = 2 times angle at the circumference)
∠EFG = ∠EFH + ∠GFH (Angle addition postulate)
∴ ∠EFH = ∠EFG - ∠GFH = 90° - 22° = 68°
∠EFH = 68°
(b) ∠EGF
Arc GH = 44°
Arc mFE + Arc + Arc mEHG = 360 (Sum of angles at the center of a circle)
Arc mFE = 360 - ( Arc + Arc mEHG )
Arc mFE = 360 - 180 - 138 = 42°
∠EGF = Arc mFE/2 (Angle at the center = 2 times angle at the circumference)
∠EGF = 42/2 = 21°
∠EGF = 21°
There are two ways to do this
1.
= 3/11
= 3 ÷ 11

2.
</span>First off, we'll interpret the fraction bar to mean "divided by." This means that 3/11 is the same as 3 divided by 11.
Second, you have to 6 decimal places in your answer, so we'll write the 3 as 3.000000 instead (a 3 with 6 zeros after the decimal point).
Now, we'll just do what the fraction bar says: divide 3.000000 by 11
