<span>When given 3 triangle sides, to determine if the triangle is acute, right or obtuse:
</span>1) Square all 3 sides.
2) Sum the squares of the 2 shortest sides.
3) Compare this sum to the square of the 3rd side.
if sum > 3rd side² Acute Triangle
if sum = 3rd side² Right Triangle<span>
if sum < 3rd side² Obtuse Triangle
1) 1,296 2,401 3,600
2) Sum = 3,697
3) </span><span>3,697 is greater than 3,600
Therefore, the triangle is acute.

Answer:
What is the question???
Step-by-step explanation:
Answer:
26.8°
Step-by-step explanation:
You find the supplementary angle by 180° - 153.2° = 26.8°
You just multiply them because “as” in the question means the same thing as “of” so it will be 7/16.
