If vertex angle is 42, and the base angles are congruent, this is an isosceles triangle, they each measure: 180-42/2. They each measure 69 degrees. The length of sides don't matter.

HELP ME (How many cubes with side length 1/2 cm does it take to fill the prism
Natalija [7]

answer:

6

step-by-step explanation:

  • for this you would find the volume and then divide by 1/2

v = l x w x h

v = (1)(2)(3/2)

v = 3

  • now, divide

3 ÷ 1/2 = 6

  • therefore, it will take 6 half cubes to fill up the container

The surface area, A, of a cylinder is given by the formula A = 2 Trh + 2nr, where ris the radius and h is the height
lord [1]

Answer:

Area = 87.9646  sq. units  from A = 28*π  sq. units.

However I cannot see this in your answer list, since the numbers look all jumbled.  Choice A. looks close to it, since there is a 28...

Step-by-step explanation:

We have a cylinder with height h = 5

radius = 2

We want the surface area of this cylinder.

A = (circumference)*h  + 2*(pi)*r^2

A = ( 4*π)*5   + 2*π*(2^2)

A = 20π + 8π  =  28 π   square units

A = 87.9646 sq.. units

Please help which property is illustrated by this example (5 . 15) . 4 = 5 . (15 . 4)
Talja [164]

Answer:

This is the commutative property of multiplication.

Step-by-step explanation:

We know this because that property states that it does not matter what order the numbers are multiplied together, as long as they are all being multiplied. So even though the numbers change on both sides, it does not affect the answer.
