Answer:
a ≈ 8.7 units
Step-by-step explanation:
Using Pythagoras' identity in the right triangle
The square on the hypotenuse is equal to the sum of the squares on the other 2 sides , that is
a² + 5² = 10²
a² + 25 = 100 ( subtract 25 from both sides )
a² = 75 ( take square root of both sides )
a = 
≈ 8.7 ( to the nearest tenth )
<u>Answer </u>
7
<u>Explanation. </u>
The triangle shown is a right triangle. One of the acute angles is given as 45°. Angles in a triangle add up to 180°
So we can get the third angle of the triangle as follows:
180 - (90+45) = 45.
From this we can conclude that, apart from the triangle being an right triangle, it is also isosceles triangle. This means that the two shorter sides of the triangle are equal.
So, the value of x is 7.
The larger number is 6 and the smaller one is 2.
0.125 but 0.13 if it asks you to round
