How many obtuse interior angles are in an obtuse triangle?

One

Step-by-step explanation:

In an obtuse triangle, at least on angle HAS to be greater than 90, and the addition simply wouldn’t add up if you had more than one, so only one angle is obtuse

One

Step-by-step explanation:

Cant have more than one otherwise you couldnt make a triangle with it.

i think it would be c

mark brainliest if im right

step-by-step explanation:

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
