Answer:
The value of x = 9
Step-by-step explanation:
Given the angles of the triangle
We know that the sum of angles of a triangle is 180°.
Therefore,
(13x+2)° + (5x-7)° + (3x-4)° = 180°
13x+2 + 5x-7 + 3x-4 = 180°
21x + 2 - 11 = 180°
21x - 9 = 180°
21x = 180° + 9
21x = 189
divide both side sby 21
21x/21 = 189/21
x = 9
Therefore, the value of x = 9
Answer:
36.12
Step-by-step explanation:
43% of 84 can be rewritten to 43% * 84 or 43/100 * 84.
43/100 * 84/1 = 3612/100
3612/100 = 36.12
The answer is 117 degrees
