How Many Degrees Is Angle 7?

Answers

Answer 1

Answer:

42°

Step-by-step explanation:

This is defined as a transversal in geometry, where one line intersects two straight lines.

It is given that one of the angles is 42°. Let the angle that measure 42° be denoted as ∠42.

∠4 ≅ ∠42 based on the alternate interior angles theorem.

∠4 ≅ ∠7 based on the vertical angles theorem.

Therefore, ∠42 ≅ ∠7 based on CPCTC.

Therefore,

m∠7 = 42°.

This depends on your definition of close.

Rational numbers are numbers that can be written as p/q where p and q are integers and q is not 0. Examples include 22/7 or 1 or 0.5.

Irrational numbers are not rational. Example include pi or square root of 2.

Two rational numbers close to -8 could be -9 and -25/3. Two irrational numbers could be -e and [tex]-5\sqrt{2}[/tex].

Then the order goes -9,-25/3 (since it is -8.333...),[tex]-5\sqrt{2}[/tex] (root 2 is around 1.4 so it is near -7),-e(around -2.7)

THANK YOU GUYS SO MUCH!!! <333333

Answers

When two angles are supplementary, it means that the two angles add up to 180°.
Thus when angle m is 34° and angle n is (2x)° when angle m and angle n are supplementary,

angle m + angle n = 180°
34° + (2x)° = 180°

*minus 34° on both sides of the eqn*

(2x)° = 180°-34°
(2x)° = 146°

To find x, divide both sides of the eqn by 2
x= 146°/2
x= 73°

I hope this helps! Feel free to clarify if you have any questions!

The value of x is:

↬ 73

Solution:

If two angles are supplementary, that means that the sum of their measures is 180°.

We're given 2 angles:

[tex]\sf{\angle m}[/tex][tex]\sf{\angle n}[/tex]

And since they're supplementary, the following holds true:

[tex]\sf{\angle m + \angle n = 180}[/tex]

Next, we know that [tex]\sf{\angle m=34}[/tex], so we plug that in

[tex]\sf{34+\angle n = 180}[/tex]

Then, ∠n = 2x:

[tex]\sf{34+2x=180}[/tex]

Which is the same as

[tex]\sf{2x+34=180}[/tex]

Subtract 34 from each side

[tex]\sf{2x=146}[/tex]

Divide each side by 2

[tex]\sf{x=73}[/tex]

Hence, x = 73
