Find the value of x PLEASE EXPLAIN
2 answers:
We can say that:
- In the first triangle, x = 57°
- In the second triangle, x = 111°
<h2>Let's go!</h2>
We must know that the sum of all the internal angles of a triangle is equal to 180°. So, just solve an equation to determine x in each triangle.
<h3>First triangle:</h3>
- 67 + 56 + x = 180 → Sum:
- 123 + x = 180 → We move 123 to the other side, changing its signal.
- x = 180 - 123 → Subtract:
- <u>x = 57°</u>
<h3>Second triangle:</h3>
- 69 + x = 180 → We move 69 to the other side, changing its signal.
- x = 180 - 69 → Subtract:
- <u>x = 111°</u>

Answer:
x = 57, x = 111
Step-by-step explanation:
The sum of the 3 angles in a triangle = 180°
Sum the 3 angles and equate to 180, that is
x + 67 + 56 = 180
x + 123 = 180 ( subtract 123 from both sides )
x = 57
---------------------------------------------------------------------
Similarly
x + 47 + 22 = 180
x + 69 = 180 ( subtract 69 from both sides )
x = 111

Answer:
93.1
24.83
24.13
2755
12.75
0.151
Step-by-step explanation:
Given :
21.1 + 45.99 + 26.0 = 93.09
15.55 + 21.61 - 12.333 = 24.827
14 + 0.8 + 9.33 = 24.13
14.5 * 190 = 2755
5.1 * 2.5 = 12.75
0.15 ÷ 0.991 = 0.151
It is a decrease because it went down in cost.
To find percent:
Find difference from original amount to present amount.
So we do 4.11-2.92
=1.19
Now find the percent:
1.19/4.11 is about 28%
28% change.
