One angle of a rhombus measures 108°, and the shorter diagonal is 9 inches long. Approximately how long is the side of the rhomb
liberstina [14]
The value of the length of the rhombus will be found as follows:
cos θ=adjacent /hypotenuse
θ=108/2=54°
adjacent = 9/2=4.5 inch
hypotenuse=length of the rhombus
thus
cos 54=9/x
x=4.5/cos 54
x=7.6558~8  inches
the answer is 8 inches

Need help with the angle measures?​
Lunna [17]

Answer:

x = 135°

Least to greatest

90°, 90°, 90°, 135° and 135°

Step-by-step explanation:

All the angles in this pentagon adds up to 540

(x - 45) + x + (x - 45) + (x - 45) + x = 540

x - 45 + x + x - 45 + x - 45 + x = 540

Collect like terms and place them on either side

5x = 540 + 45 + 45 + 45

5x = 675

Divide both sides by 5 to make x on its own

x = 135°

Angle measures of the pentagon from least to greatest

135 - 45 = 90

90, 90, 90, 135 and 135
