Vertically opposite angles formed by two lines intersecting each other are equal.

<h3>What is a transversal?</h3>

A transversal is a line that intersects two or more two lines at two or more two distinct points.

We know when two straight lines intersect each other their vertically opposite angles are of equal measure.

Given, m∠1 + m∠2 = 180° and m∠2 + m∠3 = 180°.

Therefore we can equate these two expressions.

m∠1 + m∠2 = m∠2 + m∠3.

Or,

m∠1 + m∠2 - m∠2 = m∠3.

∴ m∠1 = m∠3.

What is this? Please answer with an explanation

Colt1911 [192]

Answer:

Step-by-step explanation:

Given

f(x) = $\sqrt{x-10}$ + 11 ← substitute x = 1

f(1) = $\sqrt{1-10}$ + 11

= $\sqrt{-9}$ + 11

$\sqrt{-9}$ is not real and therefore x = 1 does not have a real output for f(x)

I really need help guys can some one plz help me it's for 10 points

11111nata11111 [884]

Answer:

$\sqrt{8}----- 2units,2units$

$\sqrt{7} ------\sqrt{5}units,\sqrt{2}units$

$\sqrt{5}-------1unit,2units$

$3------2units, \sqrt{5}units$

Step-by-step explanation:

Use pythagorean's theorem to solve each pair individually.

The instructions say that you have the two sides (a and b) and you have to match it with their hypothenuse.

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

1. $a=\sqrt{5}, b=\sqrt{2}$

Plug this into the formula.

$c=\sqrt{(\sqrt{5} )^2+(\sqrt{2})^2 }$

The square here eliminates the roots.

$c=\sqrt{5+2}\\ c=\sqrt{7}$

2. $a=\sqrt{3}, b=4$

$c=\sqrt{(\sqrt{3} )^2+(4)^2}\\ c=\sqrt{3+16}\\ c=\sqrt{19}$

3. $a=2, b=\sqrt{5}$

$c=\sqrt{(2)^2+(\sqrt{5})^2 }\\ c=\sqrt{4+5}\\ c=\sqrt{9}\\ c=3$

4. $a=2, b=2$

$c=\sqrt{(2)^2+(2)^2}\\ c=\sqrt{4+4}\\ c=\sqrt{8}$

5. $a=1, b=2$

$c=\sqrt{(1)^2+(2)^2}\\ c=\sqrt{1+4}\\ c=\sqrt{5}$

The number of students in a chess club decreased from 28 to 11. What is the percent decrease? Round your answer to the nearest p

atroni [7]

Answer:

28-11=17

28=100%

17=x

17×100/28=60,71

rounded 61%

60,71%

11/28*100=a

a-100=60,71

to nearest percent 61 i think
