Question

10. If the angles (4x +4) and 6x - 4 are the supplemantry angles find the value x​

Answer 1

The supplementary angles are (4x+4)° & (6x-4)°.

Since the sum of two supplementary is 180°,

we can write the following equation--

(4x+4)+(6x-4) = 180

or, (4x+6x)+(4-4) = 180

or, 10x+0 = 180

or, 10x = 180

or, x = 180/10

or, x = 18

Hence, the value of x is 18.

Answer 2

Answer:

we know that,

sum of supplimentary angles is 180

so, (4x+4)+(6x-4)=180

..4x+4+6x-4 = 180

10x = 180

x = 180/10

x = 18
