Answer:

0.6

Step-by-step explanation:

4 × 0.15

I can't show how to do it by typing, but in order to solve this you multiply 4 by each of those numbers and add them up together.

If done correctly, it should equal 0.6 or 0.60 (they are the same number).

)Suppose ABC is a right triangle with sides of lengths a, b, and c and right angle at C. Find the unknown side length using the

konstantin123 [22]

Answer:

$a=\sqrt{7}$

$\text{tan}(A)=\frac{\sqrt{7}}{3}$

Step-by-step explanation:

Please find the attachment.

We have been given that ABC is a right triangle with sides of lengths a, b, and c and right angle at C.

To find the side length a, we will Pythagoras theorem, which states that the sum of squares of two legs of a right triangle is equal to the square of the hypotenuse of right triangle.

$a^2+b^2=c^2$

Upon substituting our given values in Pythagoras theorem, we will get:

$a^2+3^2=4^2$

$a^2+9=16$

$a^2+9-9=16-9$

$a^2=7$

Take square root of both sides:

$a=\sqrt{7}$

Therefore, the length of side 'a' is $\sqrt{7}$ units.

We know that tangent relates opposite side of a right triangle with adjacent side.

$\text{tan}=\frac{\text{Opposite}}{\text{Adjacent}}$

We can see that 'a' is opposite side of angle A and 'b' is adjacent side.

$\text{tan}(A)=\frac{a}{b}$

$\text{tan}(A)=\frac{\sqrt{7}}{3}$

Therefore, the value of tan(A) is $\frac{\sqrt{7}}{3}$ .

Solve for x 8x−6=15 Give your answer as an improper fraction in its simplest form

kramer

Answer:

$\boxed{x = \frac{21}{8} }$

Step-by-step explanation:

=> 8x-6 = 15

Adding 6 to both sides

=> 8x = 15+6

=> 8x = 21

Dividing both sides by 8

=> x = 21/8 (In its simplest form)
