Solve for x in the diagram below

Answer:
x = 20°
Step-by-step explanation:
We know that the big angle is 90°, due to the marking on the diagram. So, we make all the angles add up to 90°. Now, we can make the x stay on one side and solve for the value.
Answer:
x= 20 degrees
Step-by-step explanation:
We know the sum of the three angles adds to 90 (because of the box in the corner)
x + 2x + x+10 = 90
Combine like terms
4x +10 = 90
Subtract 10 from each side
4x+10-10 = 90-10
4x = 80
Divide each side by 4
4x/4= 80/4
x = 20

Answer:
RD = 162 cm
Step-by-step explanation:
LD = 2 RL = 2* 54 = 108
