which best explains whether a triangle with side lengths 2 in., 5 in., and 4 in. is an acute triangle?
1 answer:
Answer:
Obtuse triangle.
Step-by-step explanation:
Side a = 5
Side b = 2
Side c = 4
Angle ∠A = 108.21° = 108°12'36" = 1.88862 rad
Angle ∠B = 22.332° = 22°19'54" = 0.38976 rad
Angle ∠C = 49.458° = 49°27'30" = 0.86321 rad
Since one angle is above 90 degrees, the triangle is obtuse triangle.
This cannot be an acute triangle.

Step-by-step explanation:
Answer:
2.8, 4.5, 5.3
numbers represent the measure of the sides of a right triangle.
2.8²+4.5²=5.3²
7.84+20.25=28.09
28.09=28.09
Answer:
4.25
Process:
- 5=4b-12
- 4b=12+5
- 4b=17
- b=
- b= 4.25
Is it to the 4th power and the second power if so it is:
