Point o is the center of this circle. what is the m< cab
a). 55°
b). 48°
c). 45°
d). 35°

B

Step-by-step explanation:

The angle on the circumference is half the angle subtended at the centre by the arc CB, that is

∠CAB = 0.5 × ∠COB = 0.5 × 96° = 48° → B

d is the correct answer

step-by-step explanation:

x= 8 because 3x = 3 * 8, and 3*8 = 24

2.2°  

step-by-step explanation:

let θ = the angle of elevation.

tanθ =77/2020

tanθ = 0.038 12

      θ = tan⁻¹0.038 12

      θ = 2.2°
