Answer:
40°
Step-by-step explanation:
360-156-124=80
80/2=40
If diagonals of a parallelogram are perpendicular to each other, this is a rhombus. A rhombus has all sides equal.
In the current scenario, the shorter rhombus is 20 cm long and has a perimeter of 80 cm
Side of rhombus = 80/4 = 20 cm
A quarter of rhombus is right angled triangle with hypotenuse being side of rhombus.
Half length of long diagonal = sqrt (20^2-10^2) = 17.32 cm
Length of longer rhombus = 17.32*2 = 34.64 cm
hi the answer is I have no clue sorryyyy
Step-by-step explanation:
For solving, use quadratic formula
Tan 18 = x/2
⇒ 0.3249 = x/2
⇒ x = 2 * 0.3249 =
⇒ x = 0.6498 ≈ 0.65
Hope it helps!
