1 answer:
Goshia [24]2 years ago

Answer:

10.08

Step-by-step explanation:

In \triangle ABC,\: m\angle ACB =90\degree

\implies \triangle ABC is a right triangle, in which side AB is hypotenuse and sides AC and BC are mutually perpendicular.

By using Pythagoras theorem:

AC^2 = AB^2 - BC^2 \\  \\   =  {(11)}^{2}  -  {(4.4)}^{2}  \\  \\  = 121 - 19.36 \\  \\  = 101.64 \\  \\  \implies \: AC= \sqrt{101.64}  \\  \\  \huge\implies \:  \red{AC=10.08}

7. Which of the following could form a unique triangle? Select all that apply.
baherus [9]

Answer:

If you are given two lengths and an angle between them (called the included angle) can you produce a unique triangle? In this interactive, you will be given different sets of two sides with the included angle. For each set, see if more than one triangle can be produced.

Step-by-step explanation:

You used side-angle-side, or SAS, to construct the triangles in the interactive. It is important to note that SAS construction will always produce one, unique triangle. It does not matter how much you flip, rotate or move the triangle, the measurements will not change.  Even though the triangle may "look" different, it still has the same angle measures and side lengths.  The orientation of a shape will never change the dimensions, just the placement.
