Question

Find the value of x if 5x°and (6x + 4)" are supplementary angles. Also, find the two angles.
​

Answer 1

Answer:

The value of x is 16 and the two supplementary angles are 80°&100°

Step-by-step explanation:

Given, two supplementary angles are 5x° & (6x + 4)°

and we know that supplementary angles forms 180°

then, 5x°+(6x+4)° = 180°

5x°+6x°+4° = 180°

11x° = 180°-4°

11x° = 176°

x = 176°/11°

x = 16

then two angles are,

5x° = 5(16)° = 80°

(6x+4)° = (6(16)+4)° = (96+4)° = 100°
