Sum of two angles that are supplementary = 180°
Let the smaller angle be = x
<h3>Their sum :</h3>
Using this let us find the measures of the smaller angle and bigger angle .
∴ The measure of the two angles are = 21° and 159° .
The unit rate is 8 pounds per dog.
128 / 16 = 8
Answer:
The answer would be 8.1
Step-by-step explanation:
For the smaller triangle, you use the pythagorean theorem. a squared + b squared = c squared.
To find one of the legs, you do 5 squared - 3 squared = b squared.
25 - 9 = b squared. (BD)
16 = b squared
4 = b
Now for the bigger right triangle. You still use the same tactic.
7 squared + 4 squared = c squared (which is AB)
49 + 16 = c squared
65 = c squared
That means c would equal: square root of 65, which is 8.0622577483 which rounds to 8.1
This is a really vague question, but all i can assume from that is that all the sides of some triangle are congruent to their respective sides on the other triangle.
