Question

Given that sin x= 1/2 and cos y = 1/2 then the value of x + y is (0°≤ x, y ≤ 90°) a. 60° b. 45° c. 90° d. 0°

Answer 1

Answer:

0 degree

Step-by-step explanation:

majak tha

ab solution:

1/2= u know

0 is zero than 90 is also zero

so easy

Answer 2

Given

$\sin(x) = 1 \div 2 \\ \cos(y) = 1 \div 2$

Let's find the values of

$x \: and \: y$

Given

$0 \leqslant x \\ y \leqslant 90$

$x = \sin^{ - 1} (1 \div 2) \\ x = 30 \: degrees$

$y = \cos^{ - 1} (1 \div 2) \\ y = 60 \: degrees$

We got the values of x and y. Now,

$x + y = 30 + 60 \\ = 90$

Therefore the value of

$x + y = 90 \: degrees$

Hence option c is correct
