To answer this question, we are assuming that the triangle is a right triangle, with sides (legs), a = 0.84m, and b = 0.63m.
Then, we can use the Pythagorean Theorem as follows:

Then, we have:
• c is the hypotenuse
,
• a, b the given legs of the right triangle

Now, to solve the equation for c, we need to take the square root from both sides of the equation:
![\sqrt[]{c^2}=\sqrt[]{(0.84m)^2+(0.63m)^2}=1.05m](https://img.qammunity.org/2023/formulas/mathematics/high-school/92c0m7lb6ku1zye25s4hjki1egub4c1uyx.png)
Therefore, c = 1.05m. The result was already given in three significant figures.
In summary, the measure of the hypotenuse of the given right triangle is 1.05m.
