Answer:
25.4 units
54.4 units
Step-by-step explanation:
Given that,
length of each side of rhombus = 30 units
interior angle = 25 x 2
= 50°
other interior angle = (360-(50x2)) / 2 = 130°
Formula to use
c² = a² + b² - ab cosC
First diagonal
√(30² + 30² - 2*30*30*cos 50)
= 25.35 u
Second diagonal
√(30² +30² - (2*30*30*(cos 130)))
= √(1800-1800cos130)
= 54.37 units
