If two angles are supplement of each other, then one of the angles must be acute

Mathematics

oksian1 [2.3K]3 years ago
7 0

Answer:

this is true

Step-by-step explanation:

a supplementary angle adds up to 180 degrees. two accute angles would equal to around 90 and two obtuse angles would add up to more than 180. two right angles are perpendicular and they could work but since the question asks about acute and obtuse, its true that one angle must be acute and the other must be obtuse for it to add up to 180.

Which property is used in the first step to solve this equation?
melomori [17]

Answer:

distributive property

Step-by-step explanation:

we know the distributive property states that the multiplication of a number (in this case, the number 4) by a sum (in this case is a subtraction:  x-6) is equal to the sum of the multiplications of that number for each of the terms that belong to the sum:

we have: 4(x-6)

we apply the distributive property, so we have

4(x-6)=4*x-4*6

4(x-6)=4x-24

The average wind speed at a local weather station is 34.8 miles per hour. The highest speed ever recorded the stations 318.0 mil
lukranit [14]

Answer:

Difference = 283.2\ miles/hour

Step-by-step explanation:

Given

Average\ Speed = 34.8\ miles/hour

Highest\ Speed = 318.0\ miles/hour

Required

Determine the difference in the highest speed and the average speed

Difference = Highest\ Speed - Average\ Speed

Difference = 318.0\ miles/hour - 34.8\ miles/hour

Difference = 283.2\ miles/hour

<em>Hence, the highest speed is 283.2 miles/hour faster than the average speed</em>

Please help! 30 points and crown! A diagonal of a cube measures StartRoot 750 EndRoot cm. The diagonal of a face measures StartR
rodikova [14]

Let length, width, and height be s.

Then diagonal of any face would be √( s² + s² ) = √( 2s² )

And we know that it measures  √( 500 ) so that's sufficient for us to figure out the length of an edge of the cube. We do not need to worry about the diagonal of the cube.

Now we have to solve √( 500 ) = √( 2s² )

Square both sides:

500 = 2s²

Divide both sides by 2:

250 = s²

Take the square root of both sides:

√(250) = s ≈ 15.8113883

Rounding to nearest tenth:

s ≈ 15.8

Final answer: 15.8

Hope this helps.
