Answer:
Step-by-step explanation:
5 1/6, 5 13/30, 5 68/90
Look into my attachment
in rhombus ABCD, ∠AOB = 90°
Look at ΔAOBthe sum of inner angles = 180°
∠BAO + ∠AOB + ∠ABO = 180°
2x + 1 + 90 + 2x + 5 = 180°
4x + 96 = 180
4x = 84
x = 21
Number of red marbles/total number of marbles
35/(35+8+7)
35/50
7/10
The probability is 7/10
