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!!!

Step-by-step explanation:
The standard equation for circle is

where point (a,b) is coordinate of center of circle and r is the radius.
______________________________________________________
Given
center of circle =((-2,3)
let r be the radius of circle
Plugging in this value of center in standard equation for circle given above we have

Given that point (1,2 ) passes through circle. Hence this point will satisfy the above equation of circle.
Plugging in the point (1,2 ) in equation 1 we have

now we have value of r^2 = 10, substituting this in equation 1 we have
Thus complete equation of circle is

Step-by-step explanation:
20a + 158+6c=you will expand the brackets
= so it is 120+60+48
20a+158+6c=120+60+48
20a+ 6c=120+60+48-158
20a+6c=70
20a divide by 20+6c divide by 6 on both side
a + c = 0.58
