Solve for x. I NEED HELP ASAP!

Mathematics
1 answer:
galina1969 [7]3 years ago
6 0

Answer:

x = 105

Step-by-step explanation:

The sum of the interior angles of a polygon is

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

Here n = 7, thus

sum = 180° × 5 = 900°

Sum the interior angles and equate to 900

x + 102 + 165 + 123 + x + 11 + 128 + 161 = 900, that is

2x + 690 = 900  ( subtract 690 from both sides )

2x = 210 ( divide both sides by 2 )

x = 105

Solve for x<br> 9 (x +2) &lt; 3(3-5)
Julli [10]

Step-by-step explanation:

9x+18 < 9-15

1)9-15= -6

9x+18 < -6

9x+18= -5

9x= (-5) - 18

9x= -23

x= 23/9=2 5/9

X=2,55556

PLEASE PLEASE PLEASE HELP!!

Problem 1) The triangles are similar because of the AA (angle angle) Similarity Theorem. The first A is the pair of congruent 39 degree angles. The second pair is unmarked, but look at where the triangles meet. They form a pair of vertical angles which are congruent. So we have two pairs of congruent angles allowing us to use the AA Similarity Theorem.

-----------------------------

Problem 2) We can use the SAS (Side Angle Side) Similarity Theorem to prove that these two triangles are similar. The angles are congruent. They are both 29 degrees. So that checks off the "A" portion of SAS. Then notice how the bottom sides are 32 and 64 for the small and large triangle respectively. They form the ratio 32/64 = 1/2, ie the smaller triangle's side is 1/2 as long as the longer counter part. Similarly, 8/16 = 1/2 as well. The ratio is constant at 1/2. This allows us to use the other "S" portions of SAS.

The circumference of a circle is 212 inches What is the measurement of the diameter of the circle round your answer to the neare
Zepler [3.9K]
Hi there!
So first to find the diameter, you will need to find the radius of the circle because the diameter is twice the length of the radius. 
Find the radius from the circumference, which is 2 \pi r.
C= 2 \pi r
212= 2 \pi r
212/2 \pi=r
Then solve for r.
Radius= 33.74
Then multiply the radius by 2 to find the diameter.
Diameter= 2 * 33.74
Diameter= 67.5 inches

Hope this helps :)
