Question

please answer it
very urgent

Answer 1

Answer:

ok here AOC is a right angla

so...x+50=90

x=90-50=40

Answer 2

Step-by-step explanation:

Given :-

angle COA= x°

angle BOC = 50°

To find :-

Fond the value of x ?

Solution :-

Given that

From the figure :

angle COA= x°

angle BOC = 50°

And it is clearly angle BOA = 90°

angle BOA = angle BOC + angle COA

=> 90° = 50°+x°

=> 90°-50° = x°

=> 40° = x°

=> x° = 40°

Answer:-

The value of x for the given problem is 40°

Used formulae:-

• The sum of the two angles is 90° then they are Complementary angles.
• The Complementary angle of X° is (90-X)°
