∠C and ∠D are vertical angles with m∠C=−x+26 and m∠D=2x−10 . What is m∠D ?

Valentin [98]

Vertical angles are made by two intersecting lines .and they are always equal
<span>∠C and ∠D are equal.
so </span><span>−x+26 =2x-10
-3x=-36
x=36/3
x=12</span>°

∠D= 2x-10
put value of x here
∠D=24-10
∠D=14°

Needd help please and thank you!! It’s 1/E just in case you couldn’t see that! Thx!

Answer:

option A

The base is e^-1

Step-by-step explanation:

Given in the question a function, f(x) = (1/e) $^{x}$

This function can also be write as.

f(x) = $(e^{-1})^{x}$

by using Negative Exponent Rule

$x^{-n}=\frac{1}{x^{n}}$

This says that negative exponents in the numerator get moved to the denominator and become positive exponents.

What is the slope of the line that passes through the points (-6, 8)(−6,8) and (-16, 33) ?(−16,33)? Write your answer in simples

Taya2010 [7]

Given:

A line passes through the points (-6, 8) and (-16, 33).

To find:

The slope of the line.

Solution:

If a line passes through two points, then the slope of the line is

$m=\dfrac{y_2-y_1}{x_2-x_1}$

The line passes through the points (-6, 8) and (-16, 33). Using the above formula, the slope of the line is

$m=\dfrac{33-8}{-16-(-6)}$

$m=\dfrac{25}{-16+6}$

$m=\dfrac{25}{-10}$

$m=-2.5$

Therefore, the slope of the line is -2.5.

An eighth-grade student said the side length 41,40 and 9 do not form a right triangle, because

balandron [24]

Answer:

Error was CHOOSING the CORRECT hypotenuse in the given sides.

H = 41 units

Step-by-step explanation:

Here, the given sides of the triangle are: 41,40 and 9

Now, as we know in a RIGHT ANGLED TRIANGLE:

The longest side is the HYPOTENUSE.

So, here H = 41

Now, by PYTHAGORAS THEOREM:

$({PERPENDICULAR)^2 + ( BASE)^2 = (HYPOTENUSE)^$

$(40)^2 + (9)^2 = 1600 + 81 = 1681 = (41)^2\\\implies (40)^2 + (9)^2 = (41)^2$

Hence, Pythagoras theorem for Right angled triangle is SATISFIED

So, error was CHOOSING the CORRECT hypotenuse in the given sides.

The correct H = 41 units and NOT 40 units.
