Question

angle x and angle y are complementary angles. If angle x=3a-5 and angle y=2a+25 then find angle x and angle y.​

Answer 1

Answer:

value of x is 37.

value of y is 53.

Step-by-step explanation:

As we know,

Sum of complementary angles is 90

2a+25+3a-5=90

5a+20=90

5a=70

a=14

value of x= 3(14)-5= 37

value of y= 2(14)+25= 53

Answer 2

Answer:

x = 37, y = 53

Step-by-step explanation:

We know that the sum of the complementary angles is 90.

So, x + y = 90

(3a-5)+(2a+25)=90

5a + 20 = 90

5a = 90 - 20

5a = 70

a = 70÷ 5

a= 14

Hence, x = 3a - 5

= 3 × 14 - 5

= 42 - 5

= 37

and y = 2 a + 25

= 2 × 14 + 25

= 28 + 25

= 53
