Are 22 42 60 a right triangle or not?
Lelechka [254]

Answer:First things first, let's explain what a right triangle is. The definition is very simple and might even seem obvious for those who already know it: a right-angled triangle is a triangle where one and only one of the angles is exactly 90°. The other two angles will clearly be smaller than the right angle because the sum of all angles in a triangle is always 180°.

In a right angled triangle the sides are defined in a special way. The side opposing the right angle is always the biggest in the triangle and receives the name of "hypotenuse". The other two sides are called catheti. The relationship between the hypotenuse and each of the cathetus is a very simple one, as we will see when we will talk about Pythagoras' theorem.

Hypotenuse calculator

If all you want to calculate is the hypotenuse of a right triangle, this page and its right triangle calculator will work just fine. However, we would also recommend to use the specific tool we have developed at Omni Calculators: the hypotenuse calculator. The hypotenuse is opposite the right angle and can be solved by using the Pythagorean theorem. In a right triangle with cathetus a and b and with hypotenuse c, Pythagoras' theorem states that: a² + b² = c².

To solve for c, take the square root of both sides to get c = √(b²+a²). This extension of the Pythagorean theorem can be considered as a "hypotenuse formula". A Pythagorean theorem calculator is also an excellent tool for calculating the hypotenuse.

Let's now solve a practical example of what it would take to calculate the hypotenuse of a right triangle without using any calculators available at Omni:

Obtain the values of a and b,

Square a and b,

Sum up both values: a² + b²,

Take the square root of the result,

The square root will yield a positive and negative result. Since we are dealing with length, disregard the negative result,

The resulting value is the value of the hypotenuse c.

Now let's see what the process would be using one of Omni's calculator, for example, the right triangle calculator on this web page:

Insert the value of a and b into the calculator

Obtain the value of c immediately

As a bonus, you will get the value of the area for such a triangle.

It is given that p varies inversely as q. If p = 12 and q = 45 find p, if q is 135.
alexgriva [62]

Answer:

p =4

Step-by-step explanation:

Given

Variation: Inversely

p = 12 when q = 45

Required

Determine p when q = 135

First, we need to determine the relationship between p and q

Since, it is an inverse variation.

The relationship is:

p\ \alpha\ \frac{1}{q}

Convert to an equation

p= k *\frac{1}{q}

p= \frac{k}{q}

Where k = constant of variation

Make k the subject

k = p * q

When p = 12 and q = 45

k = 12 * 45

k = 540

To solve for p when q = 135

Substitute 135 for q and 540 for k in p= \frac{k}{q}

p = \frac{540}{135}

p =4

Leni [432]
If it is February, then it is, as it has 28 days, but every four years, it has 29, so if you round to the nearest 7, then it is yes, but if exact, no.

Find the surface area of the regular pyramids. Round your answer to the nearest tenth.
katrin2010 [14]

Answer:

S.A = 147.35 cm²

Step-by-step explanation:

Surface area of the triangular pyramid = base area + ½(perimeter of base*slant height)

Base area = ½*bh

b = 7 cm

h = 6.1 cm

Base area = ½*7*6.1 = 21.35 cm²

Perimeter of triangular base = 7 + 7 + 7 = 21 cm

slant height = 12 cm

Plug in the values into the equation

S.A = 21.35 + ½(21*12)

S.A = 21.35 + 126

S.A = 147.35 cm²
