Answer:diameter of circle A is
(2r - 10) centimeters while Answer:diameter of circle B is 2r
Step-by-step explanation:
Diameter = radius/2
Circle A has a radius that is 5 centimeters less than the radius of Circle B. It means that if the radius of circle B is 5 centimeters, then the radius of circle A would be (r - 5) centimeters. Also,
The diameter of circle B would be
2 × r = 2r centimeters
Therefore, the diameter of circle A would be expressed as
2(r - 5) = (2r - 10) centimeters
Step-by-step explanation:
F and C, I think those are the only ones
Because this triangles is isosceles (AB=AC),∠B=∠C=47⁰.
∠A=180-47-47= 86
∠BAD=∠CAD= y =86/2=43⁰
Δ BAD
Sum of 3 angles = 180⁰
47+43+x=180
x=180-90=90⁰
x=90⁰
x=90⁰, y=43⁰
