Remark

Only if you define it into existence. The square root of a negative number is does not exist in the real world.

√(-1) is defined to be i

That is what is termed a complex number.

No, and therefore, the answer to a negative square root will be "i" which stands for "imaginary" (a group of numbers).

Example:

$\sqrt{-2} = i$

In a right triangle, one acute angle is 22º and the hypotenuse is 70 cm. Find the

meriva

Answer:

Adjacent leg (In relation to the angle that is measure 22 degrees)= 70*Cosine 22 or 64.9; Opposite leg (In relation to the angle that is measure 22 degrees)=70* Sin 22 or 26.22

Step-by-step explanation:

The other angle measure is 90-22 or 68.

To find the length of the adjacent leg (a) use cosine. Remember cosine is Adjacent leg over hypotenuse.

Cosine 22= a/70- Multiply by 70

70* Cosine 22=a or about 64.9

To find the length of the opposite leg (o) use sine. Remember sine is Opposite leg over hypotenuse

Sine 22= o/70

70*Sine 22=o

o= about 26.22

The measure of the angle's supplement is 40° more than three times that of its complement. find the measure of the angle descr

Lemur [1.5K]

Angle is x. sup - adds up to 180. comp adds up to 90

180-x = 3(90-x)+40
180-x = 270-3x+40
180-x = 310-3x
180+2x = 310
2x = 130
x=65

<h3>What is fraction?</h3>

A fraction can be a portion or section of any quantity out of a whole, where the whole can be any number, a specific value, or a thing.

Giraffe height = 6 feet

Height grew in 7 months= 1.75 feet

Giraffe's height in 7 month = 7.75 feet

Giraffe's height, 1 feet= $\frac{7}{7.75}$ month

= 0.9032 months

Giraffe's height, 15 feet= 0.9032 x 15 month

= 13.548 month

= 13 months 16 days approx.

= 1 year 1 month 16 days

Hence, the age of giraffe will be 1 year, 1 month and 16 days
