Answer:

  45°

Step-by-step explanation:

The acute angles of a right triangle are complementary. The base angles of an isosceles triangle are congruent. If x is the measure of the base angles, this requires ...

  x = 90-x . . . . . the base angle is congruent to the other base angle

  2x = 90 . . . . . add x

  x = 90/2 = 45 . . . . divide by 2

The measure of a base angle of an isosceles right triangle is 45°.

Find the volume of a cone with a height of 6 in and a base radius of 4 in
Neko [114]

Answer:

The answer is

<h2>100.5 in³</h2>

Step-by-step explanation:

The volume of a cone is given by

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

where

r is the radius

h is the height of the cone

From the question

h = 6 in

r = 4 in

The volume of the cone is

V  =  \frac{1}{3}  \times  {4}^{2}  \times 6\pi \\  =  \frac{1}{3}  \times 16 \times 6\pi \\  =  \frac{1}{3}  \times 96\pi \\  = 32\pi \\  = 100.530964

We have the final answer as

100.5 in³

Hope this helps you

Scarlett is throwing a end of the year party for 2013
galben [10]

Answer:

7.5 pounds.

Step-by-step explanation:

the answer is 7.5 ponds because if each slider has 2 oz. then we can find the total number of oz. needed by multiplying by 60. This gets 120 oz that Scarlett needs in total. Since there are 16oz in a pound we divide 120 by 16 to find the number of pounds needed.
