Question

जर sinA = cos B तर A+B = ?
1) 0°
2) 30°
3) 60°
4)90°
please answer fast​

Answer 1

Answer:

(4) 90°

Step-by-step explanation:

Sin A = Cos B

Sin 45° = Cos 45°

i.e. $\frac{1}{\sqrt{2} } =\frac{1}{\sqrt{2} }$

A = 45°

B = 45°

∴A + B = 45° + 45° = 90°

Answer 2

Answer:

90° is answer

Step-by-step explanation:

SinA= cosB

sinA and cosB both are equal on 45°

A+B= 45+45

= 90°

so the answer is 90°
