Someone help me with this I would really appreciate it !

V = 126

Step-by-step explanation:

Volume of a pyramid is V =

l = length

w = width

h = height

width is 6 mi

length is 7 mi

height is 9 mi

V =

V = 126

c. 65°

step-by-step explanation:

we are given a triangle with two known angles, 62° and 53°, while the third angle x is unknown and we are to find its value.

we know that the sum of angles in a triangle is equal to a total of 180 degrees. so we can write it as:

x + 62° + 53° = 180°

solving to find the value of x:

x = 180 - (62 + 53) = 65°

therefore, the value of x in this triangle is 65°.
