Answer:
First drawing - answer is: D: DG, FG and DE
Second drawing - answer is: π (pi)
Third drawing - answer is: 70° ( If you mean on measure of central angle which is corresponing to the arc CB)
Fourth drawing - answer is: y=55° ( If you mean that the value of angle ∠AOB=70° )
Step-by-step explanation:
For the second drawing
arc AB = (r · π / 180) · α = (3 · π/180) · 60 = (180 · π) / 180 = π
For the third drawing
∠CAB is peripheral angle of the central angle ∠CFB.
∠CFB= 2·∠CAB= 2· 35° = 70°
Good luck!!!
Answer:
21
Step-by-step explanation:
One third of the number can be represented by 1/3t.
To make an equation, set this equal to 7.
1/3t = 7
Then, solve for t by dividing each side by 1/3:
1/3t = 7
t = 21
So, the number is 21.
