Answer:
∠SQR = 1/2 m ∠SR = 1/2 x 86 = 43°
C:
6*2 = 2.5c
c = 4.8
b:
Cannot be solved until the measure of one other angle in the X is added.
1 : 100,000
Because there are 100cm in a m and 1000m in a km
100 x 1000 = 100,000
Answer: 1296 cm³
Step-by-step explanation:
Since, the volume of a square pyramid is,

Where a = side of the square base,
h = height of the pyramid,
By the given diagram,
a = 18 cm,
h = 12 cm,
Hence, the volume of the given pyramid,



cube cm.
⇒ First option is correct.
