86Work Out The Size Of Angle X.51

Answers

Answer 1
The answer would be 129 degrees!

x + 51 = 180
x + 51 - 51 = 180 - 51
x = 129

the angle below 51 degrees would be complementary angles with x and so it would also have 51 degrees above x. 51 degrees and x are supplementary angles. supplementary angles are two angles that have a sum of 180.
hope that helps!!
Answer 2

The measure of angle x is 129 degrees.

Given that the two parallel lines making angles 51° and x°, these are consecutive angles between the parallel we need to find the measure of x,

So, we know that,

If two lines are parallel, the consecutive interior angles formed by a transversal are supplementary, meaning their measures add up to 180 degrees.

In this case, we have one angle measuring 51 degrees. Let's denote the other angle as x degrees.

Since the angles are consecutive, their measures add up to 180 degrees:

51° + x° = 180°

To find the value of x, we can solve this equation by isolating x:

x° = 180° - 51°

x° = 129°

Therefore, the measure of angle x is 129 degrees.

Find the measure of an exterior angle of a regular 50-gon.

Answers

Answer:

7.2º

Step-by-step explanation:

all polygon's exterior angles measure 360º, so we just need to divide by 50 to get and individual exterior angle measure. 360/50=7.2º

The measure of an exterior angle of a regular 50-gon should be considered as the 7.2º.

Calculation of an exterior angle:

Since we know that

All polygon's exterior angles should have the total of 360º,

So basically we divide 360 by 50 so that the measure of an exterior angle should be determined

i.e.

[tex]= 360\div 50[/tex]

= 7.2 degrees

Hence, The measure of an exterior angle of a regular 50-gon should be considered as the 7.2º.
