Write a two-column proof.

Mathematics
1 answer:
Tpy6a [65]3 years ago
5 0

Answer with Step-by-step explanation:

Since we have given that

Angle 12 and angle 11 are complementary.

Mathematically, it is expressed as

\angle 12+\angle 11=90^\circ ------------(1)

measure of angle 10 + measure of angle 11 = 90 degrees.

Mathematically, it is expressed as

\angle 10+\angle 11=90^\circ ----------------(2)

From eq(1), and eq(2), we get that

\angle 12+\angle 11=\angle 10+\angle 11\\\\\angle 12=\angle 10

Hence, angle 12 is congruent to angle 10.

USLUIT il<br> Find x.<br> 45°<br> 30°
IceJOKER [234]

Answer:

111°

Step-by-step explanation:

  • All these are parallel lines, so the 36° angle is equal to the 36° angle inside the big triangle because they are vertically opposite.

  • Ignore the line cutting between 45° and the 30° and consider it as one triangle
  • Add them to get 75°
  • Now you have two known angles 75° and 36°
  • To get angle <em>x</em><em> </em>add 75° and 36° to get 111°
  • Because x° is an exterior angle and exterior angles equal to the sum of interior angles opposite it inside the triangle.

What is the domain of <br> F(x)=√x ?<br><br> (PLEASE HELP ASAP)
leva [86]

Option C. all real numbers greater than 0 is the correct answer

Further explanation:

Domain is the set of all inputs on which the function is defined or real.

The given function is:

f(x)=\sqrt{x}

As the function involves a square root, we have to avoid negative numbers.

  • All positive real numbers will produce defined output so the positive real numbers will be included in the domain.
  • If we look at negative real numbers, we will be taking square root of a negative number which will not result in a real number

So the domain will only include positive real numbers.

Hence, Option C. all real numbers greater than 0 is the correct answer.

Keywords: Domain, Domain of radical functions
