Answer:
x = 8
y = 8
Step-by-step explanation:
This is a special right triangle with angle measures 45-45-90
The side lengths for this triangle are as follows
a (the side lengths that see angle measure 45)
a (the side length that sees angle measure 90)
one of the side length which sees angle measure 45 is given as 8
so a = 8 as well as x = 8
therefore y = 8

Answer:
m∡ZA = 51°
m∡ZB = 39°
Step-by-step explanation:
∡ZB = 'b'
∡ZA = '12 + b'
b + 12 + b = 90
2b + 12 = 90
2b = 78
b = 39
12 + 39 = 51
Answer:
Volume of rectangular prism = 1200 cubic inches
Step-by-step explanation:
Given that:
Length of rectangular prism = 10 inches
Width of rectangular prism = 8 inches
Height of rectangular prism = 15 inches
Volume of rectangular prism = Length * Width * Height
Volume = 10 * 8 * 15
Volume = 1200 cubic inches
Hence,
Volume of rectangular prism = 1200 cubic inches
