Students were asked to answer a question at schools and to mention what is most important for them to succeed. One which response stood out from the rest was practice. Persons who surely are successful do not become successful by being born. They work hard and persistence their lives to succeeding. If you tend to complete your goals, keep this in mind! followed below are one of the answer and question example that you could certainly utilise to practice and develop your understanding and also give you insights that could just guide you to keep up your study in school.

## Question:

Which side of DEF is the longest ? Please help

## Answer:

∠D= 87°, ∠E = 50°

Sum of three angles in a triangle is 180°

∠F = 180 – (∠D + ∠E)

∠F = 180 – (87 + 50)

∠F = 180 – 137

∠F = 43°

Side opposite to greatest angle is the longest side.

Among angle D, E and F, angle D is the greatest angle

So side opposite to angle D is the longest side which is EF

Option B is the answer

They could definitely hopefully guide the student answer the question by make use of the questions and answer examples. You can then have a discussion with your classmate and continue the school learning by studying the question altogether.
