Answer: Option C. x 1 2 3 y 3 6 9
Step-by-step explanation:
Compare the longest side to the other 2 shorter sides of the triangle:
10² : 7² + 8²
= 100 : 113
Since 7² + 8² > 10², it is an acute triangle.
Answer:
B.-7.34
Step-by-step explanation:
Because it's a repeating number
Either of two Angles whose sum is 180 degrees
Look at the picture.
We have the similar triangles (AAA). Therefore the lengths of the sides are in proportion:

<em>multiply both sides by 8</em>
