Find the value of x please

Mathematics
1 answer:
madreJ [45]3 years ago
4 0

Okay <em>we need to know the number of degrees in this shape first</em> in order to find x.

The formula to find the # of degrees in any polygon is

180 ( n - 2 )

n = the number of sides the figure has

This figure has 8 sides

180 ( 8 - 2 )

180 (6) = 1080°

This figure is 1080°

To find x, let's <u>subtract all the other degrees</u> they gave us

<em>1080° - 124° - 136° - 132° - 129° - 116° - 158° - 141° = 144°</em>

x = 144°

I hope I helped!

If two sides of a triangle are 3 cm and 5 cm in length, which could NOT be the measure of the third side? A) 2 cm B) 3 cm C) 4 c
enot [183]

In geometry, there is a theorem that states: The sum of any two sides of a triangle is greater than that of the third

Let's try to plug in and find if any two sides added together will be greater than the third:


a) 2 cm

3+5=8 and 8>2 [acceptable]

2+3=5 but 5=5 [not acceptable]

2+8=10 and 10>5 [acceptable]

b) 3 cm

3+3=6, 6>5 [good]

3+5=8, 8>3 [good]

.....

etc


We found that the answer has to be 2cm, because if we were to add a side of 2cm with 3cm, it would equal to the third side and the theorem states that the sum has to be greater


Hope this helped :) If so, leave a rating :)
