Classify the triangle. scaleneequilateralisosceles

It is a Scalene triangle.

Step-by-step explanation:

Given : Triangle with sides 3 , 4 , 5 units .

To find : Classify the triangle.

Solution : We have given triangle with sides 3 , 4 , 5 units .

Scalene triangle : Triangle which have all sides different.

Equilateral triangle :  Triangle which have all sides equal .

Isosceles triangle : Triangle which have two sides equal .

Since the given triangle have all different sides like 3 , 4 , 5 units.

Therefore, It is a Scalene triangle.

7.9m and 4.3°

step-by-step explanation:

let east be +x and north be +y, x = distance * cos θ, y = distance * sin θ  

for 3.5 south, y = -3.5  

for 8.2, x = 8.2 * cos 30 and y = 8.2 * sin 30  

for 15 west, x = -15  

total x = 8.2 * cos 30 – 15 ≈ -7.9  

total y = -3.5 + 8.2 * sin 30 = 0.6  

magnitude = [(8.2 * cos 30 – 15)^2 + 0.6^2)]^0.5  

the magnitude is approximately 7.9 m  

tan θ = y/x = 0.6/-7.9  

the angle is approximately 4.3˚ north of west

answer:

24pi or letter c
