1/3(x) = 5/6(x) - 15
2/6(x) = 5/6(x) - 15
15 = 1/2(x)
x=30

Please answer I will give you brainliest!!! Find the angles of the rhombus if the ratio of the angles formed by diagonals and th

Aleksandr-060686 [28]

Answer:

one angle : 6x=6(90/11)=540/11 (49.1 rounded to the nearest tenth)

other angle=5(90/11)=450/11 (41 degrees rounded to the nearest ones)

Step-by-step explanation:

ratio of the angles 6:5

when you draw diagonal inside a rhombus it creates four right angled triangle

one angle=90

6x+5x=90 ( the other angles is complimentary)

11x=90

x=90/11

one angle : 6x=6(90/11)=540/11 (49.1 rounded to the nearest tenth)

other angle=5(90/11)=450/11 (41 degrees rounded to the nearest ones)
