50. If angles are complementary, what’s value of x?

maks197457 [2]

Answer:

x = 14

Step-by-step explanation:

For complementary angles, the sum of two angles is equal to 90 degrees.

We have,

$m\angle ABC = 4x-10\\\\m\angle DBC = x+30$

ATQ,

$4x-10+x+30=90$

Taking like terms together,

4x+x =90-30+10

5x = 70

x = 14

So, the value of x is 14.
