Question

A triangle can be constructed by taking two of its angles as: (a)(b) 70⁰, 115⁰ (c) 135⁰, 45⁰ (d) 90⁰, 90⁰

• A. $110°,40°$
• B. $70°,115°$
• C. $135°,45°$
• D. $90°,90°$

Answer 1

The correct option is A

$110°,40°$

We know that from the angle sum property the sum of all angles of the triangle is equal to$180°$.

so,$110°+40°=150°$

The third angle$=30°$

Hence, option a is correct one.
