Answer:

106°

Step-by-step explanation:

ΔDCB is equilateral which means it must also be equiangular; each angle is 60°

ΔABD is isosceles because AB=BD so ∡ADB=∡BDA

∡ABD = 180-(67 + 67) = 46

∡ABC = ∡ABD + ∡DBC

∡ABC = 46 + 60

Answer:

= $6\sqrt{3}$

Step-by-step explanation:

This triangle is the same as a right triangle rotated around.

Pythagorean Theorem applies to this (because it's a right triangle)

$a^{2} +b^{2} =c^{2}$

$36+b^{2} =144$

$144-36=108\\b^{2} = 108\\\sqrt{108} = 10.39\\ = \sqrt{b^{2} } \\b=10.39$

x=10.39

The water tank in the diagram is in the shape of an inverted right circular cone. The radius of its base is 16 feet, and its hei

Answer:

6433.98 ft

Step-by-step explanation:

In order to find what 25% of the tank's capacity is, we know to know the full capacity of the tank then take 25% of that. The volume formula for a right circular cone is

$V=\frac{1}{3}\pi r^2h$

We have all the values we need for that:

$V=\frac{1}{3}\pi (16)^2(96)$

This gives us a volume of 25735.93 cubic feet total.

25% of that:

.25 × 25735.93 = 6433.98 ft

The equation $1.50p + $5.00 = $14.00 shows the total cost of picking p pounds of blueberries at a local blueberry farm. How many

julia-pushkina [17]

First we need to subtract $5 from both sides. That gives us the new equation 1.50p = 9. Then, divide 9 by 1.5, which gives you the answer. 9/1.5 = 6.
