Find the variable

11w + x

Step-by-step explanation:

Answer:

Step-by-step explanation:

The value of x is 15, y is 5 and z is 17 units in the given triangle.

Trigonometry is a branch of mathematics that studies relationships between side lengths and angles of triangles.

First let us find value of y

We know that hypotensue / leg = leg/y

20/10 = 10/y

Apply cross multiplication

20y=100

y=5

Now let us find x value

20-y=x

20-5=x

x=15

The altitude is √5.15= √75

=8.6

Now by pythagoras theorem, we find value of z

x²+75 = z²

15²+75 = z²

225+75= z²

300= z²

z=17.3

Hence, the value of x is 15, y is 5 and z is 17 units in the given triangle.

Answer:

40% I think because it is easy to turn a number into percentage.

Answer:

Step-by-step explanation:

We will need to rewrite the Pythagorean Theorem

A^2 + B^2 = C^2

Substitute. tIn this case:

18^2 + x^2 = 82^2

Subtract 18^2

x^2 = 82^2 - 18^2

In order to get x alone, take the root:

x = sqrt(82^2 - 18^2)

And solve:

x = 80

========================================================

Explanation:

The "move down 7" means the y coordinate 8 becomes 8-7 = 1

We subtract 7 from the y coordinate.

The "move right 8 units" means we add 8 to the x coordinate to get 0+8 = 8

Therefore, the point (0,8) moves to (8, 1)

The length of EF from the given diagram is 2.98

The formula for calculating the length of an arc is expressed as;

L = rtheta

where

r is the radius

theta is the subtended angle

Given the following

r = 7/9π

theta = 70 degrees

L = 70/360 * 2 * 7/9π * π

L = 2.98

Hence the length of EF is 2.98

Answer: B. 8/100

      Let's give 5/10 a denominator of 100 since 58/100 does, so they have common denominators:

5/10 * 10 = 50/100

      Now, we can subtract 50/100 from 58/100 to find the unknown fraction:

58/100 - 50/100 = 8/100

      This gives us an answer of,

                   B. 8/100
