Answer:

1) Sometimes

2) Never

Step-by-step explanation:

1) you could have two angles add up to 180 degrees and one of them could be less than 90

example, x = 140° and y = 40°

2) if two angles are complementary then their sum is 90° so neither angle must be less than 90°, thereby making them both acute angles

Answer:

1. If x and y are supplementary angles, then y is sometimes acute because supplementary angles are angles that add up to 180 degrees. So, y can be acute while x can be obtuse, y can be obtuse while x can be acute, or both can be right angles.

2. If x and y are complementary angles, then x is never obtuse. Complementary angles are angles that add up to 90 degrees, and obtuse angles are angles over 90 degrees, so it's impossible to have an obtuse angle as a complementary angle.

The volume of a cube can be calculated using the formula V = s^3, where s is the side length. What is the volume of a cube with
kumpel [21]

Answer:

Volume of a cube with side length 1/3 of a meter = 1/27m^3

Step-by-step explanation:

Let

1 meter = m

V = s^3

Where,

V= volume of a cube

s= side length

s = 1/3 of a meter

= 1/3 × m

= 1/3m

V = s^3

= 1/3^3

= 1/3m * 1/3m * 1/3m

V = 1/27m^3

Volume of a cube with side length 1/3 of a meter = 1/27m^3

5PLSS NEED HELP.........
love history [14]

Answer:

  acute: 7, 9

  right: 8, 10

  obtuse: 5, 6

Step-by-step explanation:

When you have a number of identical calculations to do, it is convenient to do them in a spreadsheet. You only need to enter the formula once and copy it as many times as needed.

The attachment shows the "sum of squares" calculation and comparison to the square of the longest side. When the sum is too small, the longest side is longer than needed for a right angle, so the triangle is obtuse. When the sum is too great, the longest side is too short for a right angle, so the triangle is acute.

We have skipped the tedious arithmetic and shown the results in the attached table.

What is the sum of 5ft 9in + 12ft 3in
baherus [9]
We already know that 1 ft= 12 in.

5 ft 9 in= 5 ft* (12 in/1 ft)+ 9 in= 69 in

12 ft 3 in= 12 ft* (12 in/1 ft)+ 3 in= 147 in

5 ft 9 in+ 12 ft 3 in= 69 in+ 147 in= 216 in

The final answer is 216 in.

Hope this would help~
