Some recent schools question and answer asked over students to express what they agree to is the most important concern for a student to do in order for you to obtain success. Of the many answers, the one which that stood out was practice. People who are successful do not become successful by being born. They work hard and dedicate their lives to succeeding. This is how you can reach your goals. Below are one of the answer and question example that you could possibly benefit from to practice and develop your practical knowledge and also give you insights that may assist you to keep up your study in school.

## Question:

What is the value of x?

12 units

15 units

20 units

24 units

## Answer:

**Answer:**

The value of x is 15 units.

**Step-by-step explanation:**

In the given triangle RSQ and ΔRST it is given that

∠RTS ≅ ∠SRQ ≅ 90°

∠RSQ is common in two triangles Δ RSQ and Δ RST.

Therefore two angles are equal so both the triangles are common.

From this property we opposite sides of the corresponding angles will be in the same ratio.

SR/SQ = ST/SR

x/(9 + 16) = 9/x

By cross multiplication on each side of the equation

x² = 25×9 = 225

x = √225 = 15

Therefore measurement of x is 15 units.

They can hopefully guide the student take care of the question by making use of the questions and answer examples. Then might possibly carry out some sharing in a group discussion and also study with the classmate with regards to the topic, so another student also have some enlightenment and still keeps up the school learning.
