Answer:
The answer to your question is Perimeter = 287.3 in
Step-by-step explanation:
AB = 90 in
BC = 80 in
∠B = 50
Perimeter = ?
Process
1.- We need to find AC using Law of sines
A = 42.9 ≈ 43
The sum of the internal angles in a triangle equals 180°
A + B + C = 180°
43 + B + 50 = 180
B = 180 - 43 - 50
B = 87°
AC = 117.3
2.- Find the perimeter
Perimeter = AB + BC + AC
Perimeter = 90 + 80 + 117.3
Perimeter = 287.3 in
Answer:0.175 m/s
Step-by-step explanation:
Given
Two sides of length 9 and 13 m
angle between them is increasing at an angle of 0.02 rad/min
rate of increasing of third at
let a=9
b=13
c=unknown side
Now using cos rule of triangle
Differentiating both sides we get
at
c=11.53 m
substituting values we get
