Answer 1

Solution :-

Since , the two ∆'s DEF & STU by the SAS congruence.

So , here

• Sides DE & TU are equal

• Angles EDF & SUT are equal

• Sides DF & SU are equal

♦ In other form :-

→ 3x + 10 = 5t

→ 2x + 15° = 5x - 60°

→ DF = SU

Firstly finding the value of x

➵ 2x + 15° = 5x - 60°

➵ 5x - 2x = 60° + 15°

➵ 3x = 75°

➵ x = 75° ÷ 3

➵ x = 25°

Now , 3x + 10 = 5t

Substituting the value of x we have ,

⇒ 3x + 10 = 5t

⇒ 3 ( 25 ) + 10 = 5t

⇒ 75 + 10 = 5t

⇒ 85 = 5t

⇒ t = 85 ÷ 5

⇒ t = 17

Therefore , x = 25° & t = 17
