Question

If Q is 45 degree then find A and B​

Answer 1

Answer:

Angle PQR = 45

So applying Trignometric ratio for B

= Sin 45 = P/H = B/6

= 1/√2 = B/6

= 3√2 = B

Applying Trignometric ratio for A

= Cos 45 = B/H = A/6

=1/√2 = A/6

= A = 3√2

{ P = Perpendicular, B= Base, H= Hypotenuse}

Saying thanks for anybody help donesnt make you small

Answer 2

Answer:

$a = b = 3 \sqrt{2}$

Step-by-step explanation:

Q = 45°

P = 180-(90+45)° = 45°

$\sin(q) = \sin(45) = 1 \div \sqrt{2} \\ = a \div 6 = 1 \div \sqrt{2} \\ = a = 6 \div \sqrt{2} = 3 \sqrt{2}$

Same is for a as both angles are equal hence it is an isosceles right angle triangle.
