An isosceles triangle has an angle that measures 92° which other angles could be in that isosceles triangle choose all that appl
nignag [31]

Answer:

44

Step-by-step explanation:

The two base angles cannot both be 92 degrees because they would add up to 184 which is more degrees than any triangle has. The apex angle (the top angle) therefore has 92 degrees.

The base angles are equal and found as follows.

2*b + 92 = 180                 Subtract 92 from both sides

2b +92-92 = 180-92

2b = 88                           divide by 2

2b/2=88/2

b = 44

The only angle measurement that fits is 44

Find the volume of the sphere with a radius, r, of 3/2 feet and π ≈ 3.14.
nalin [4]

Answer:

V= 14.13

Step-by-step explanation:

Information needed:

V= 4/3\pir^3

\pi= 3.14

r= 3/2

Solve:

V= 4/3\pir^3

V= 4/3(3.14)(3/2)^3

V= 4/3(3.14)(27/8)

V= 14.13
