Please help! Name an angle adjacent and congruent to angle AOC ( diagram in picture)

kipiarov [429]

Answer:

Angle DOC

Step-by-step explanation:

Since angle AOC and angle DOC are ajacent angles that form a straight line, they are supplementary to each other.

By the definition of supplementary angles, you can determine that angle AOC + angle DOC = 180.

Also notice that angle DOC is a right angle (90 degrees), so you can also determine that angle AOC is also a right angle since they are supplementary.

Find the length of the unknown side. Round your answer to the nearest tenth.

Paraphin [41]

Answer:

<em>The correct option is: 11.5</em>

Step-by-step explanation:

Suppose, the length of the unknown side is $x$

So, here the length of hypotenuse is 14 and the lengths of other two sides are 8 and $x$ .

As the given triangle is right angle triangle, so <u>using Pythagorean theorem</u>, we will get.........

$8^2+x^2= 14^2\\ \\ 64+x^2=196\\ \\ x^2=196-64=132\\ \\ x=\sqrt{132}=11.489...\approx 11.5$

<em>(Rounded to the nearest tenth)</em>

So, the length of the unknown side is 11.5
