Question

 If two angles of a triangle are 45⁰ and 65⁰, then the third angle is

70⁰

105⁰

65⁰

75⁰​

Answer 1

Answer:

Ans = 70°

Step-by-step explanation:

Let the third angle be x°

45°+65°+x° = 180°(Angle sum property of triangle)

110°+x°=180°

x°=180°-170°

x°=70°

Answer 2

Given

⇒∠A=45°

⇒∠B=65°

To Find

⇒∠C= x°

We Know That

⇒The Sum of all interior angle in triangle is 180°

⇒∠A+∠B+∠C=180°

Now Put the value

⇒45°+65°+∠C=180°

⇒110° + ∠C = 180°

⇒∠C = 180°-110°

⇒∠C = 70°

Answer

⇒Third angle is 70°

Now Check our answer

⇒∠A+∠B+∠C=180°

Now Put the value

⇒∠C = 70°

We get

⇒45°+65°+70°=180°

⇒110°+70° = 180°

⇒180° = 180°

LHS = RHS
