Answer:
3320in²
Step-by-step explanation:
heron formula = √s(s-a)(s-b)(s-c)
when s = (a+b+c)/2
s = (16+35+25)/2 = 76/2 = 38
heron formula = √s(s-a)(s-b)(s-c) = √78(78-16)(78-35)(78-25) = √78(62)(43)(53) = √11021244 = 3319.82589905≈3319.8in²(nearest tenth)
A) =27.2
b) = 30.1
c) =31.2
d) =36.6
answer = D
Answer:
x = 55°
Step-by-step explanation:
The sum of the 3 angles in a triangle is 180°
Subtract the sum of the 2 given angles from 180 for x
x = 180° - (75 + 50)° = 180° - 125° = 55°
Answer:
c
Step-by-step explanation:
mass will never change only weight will as weight is dependent on gravitational field strength
