Find the value of x. 3x, 2x, 55

Mathematics
1 answer:
SOVA2 [1]3 years ago
7 0

The sum of the measures of the angles in a triangle is 180°.

Therefore we have the equation:

2x° + 3x° + 55° = 180°

5x° + 55° = 180°    <em>subtract 55° from both sides</em>

5x° = 125°     <em>divdie both sides by 5</em>

x° = 25°

<h3>Answer: x = 25</h3>

Answer:

a=35, b=14, c=5

Step-by-step explanation:

b+6=20, b+6-6=20-6, b=14

4c-6=14, 4c-6+6=14+6, 4c=20, 4c/4=20/4, c=5

a triangle's angles always add up to 180, 180-55-90(the square means right angle)=35
