Question

one angle of a right angled triangle is 42 find the third side of angle​

Answer 1

$\huge\star{\pink{\underline{\mathfrak{answer}}}}$

Let ABC is an right angled triangle , right angle at A.

So, <A = 90°

<B = 42° { given}

<A+<B+<C = 180°

90° + 42° + <C= 180°

<C = 180° - 132°

<C = 48°

Hence the third angle of the triangle is 48°.

Answer 2

Answer:

total angle of triangle = 180°

this is right angled triangle. So, it's one angle is 90°

their third side of angle = 180° - ( 90° + 42° )

= 180° - 132°= 42° ans
