If the length of the two sides in a triangle is 2 cm by 5 cm, then the value that can be the length of the third side is A )1cm
B) 2cm
C) 3cm
D) 4cm

pls answer only if you're sure ab it pleas

b. x + 1

step-by-step explanation:

i'am smart

well what did you do it matters what you did : )

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

depends what are you allowed to do ?
