Answer:
B
Step-by-step explanation:
Since the triangle is right use the sine/ tangent ratios to solve for x and y
note sin60° = and tan60° =
sin60° = =
ysin60° = 3
y × = 3
multiply both sides by 2 and divide by
y v= 6 = 6
tan60° = =
xtan60° = 3
x × = 3
divide both sides by
x = 3 = 3
Answer:
C
Step-by-step explanation:
Volume of a pyramid = 1/3 base area * height
