Solve for x. x = ___°

Mathematics
1 answer:
irina [24]3 years ago

x = 109

this is pentagon

the sum of the interior angles of a polygon is

sum = 180°( n - 2) where n is the number of sides.

sum = 180° × 3 = 540° thus

x + 121+ 108 + 102 + 100 = 540

x + 431 = 540

subtract 431 from both sides

x = 540 - 431 = 109

Answer:

Step-by-step explanation:

x − 5 = 0   ⇒   x1 = 5

3x + 1 = 0   ⇒   x2 = −1

3

≈ −0.333333

Factorization:

(x − 5)(3x + 1) = 0

Standard form:

3x2 − 14x − 5 = 0

Extrema:

Min = (2.333333, −21.333333)

Answer:

( 3 x + 1 )  ( x − 5 )

The measure of &lt;1 = 20x + 21 and the measure of &lt;2 = 30x - 29.
geniusboy [140]

Answer:

Both equal 121 degrees

Step-by-step explanation:

Vertical angles are equal, and  and 2 are indeed vertical angles.  They are the "top" and "bottom" of the x formed.  So you can use this.

angle 1 = angle 2

20x + 21 = 30x - 29

50 = 10x

5 = x

So just plug this in.

20x + 21

20(5) + 21

121

30x - 29

30(5) - 29

121

So both are 121.
