Since the deepest point of Death Valley is below sea level, its altitude is negative. So, the difference between the altitudes is
Subtracting a negative means to add, so we have
Answer:
The answers for this are as followed:
Area = 906.12058 (Rounded to the nearest tenth = 906.1)
Perimeter = 138.94608 (Rounded to the nearest tenth = 138.9)
Semiperimeter = 69.47304 (Rounded to the nearest tenth = 69.5)
Step-by-step explanation:
This is an Acute Scalene Triangle, with the side and angle measurements being:
Side A = 49
Side B = 40.17851 (Rounded = 40.2)
Side C = 49.76757 (Rounded = 49. 8)
------
Angle ∠A = 65° = 1.13446 rad
Angle ∠B = 48° = 0.83776 rad = 4/15π
Angle ∠C = 67° = 1.16937 rad
------
∠C = 180° - A - B = 1.16937 rad = 67°
b = a·sin(B)/sin(A) = 40.17851
c = a·sin(C)/sin(A) = 49.76757
In order to find the area, just use the equation:
Answer:
x=7,3
Step-by-step explanation:
x^2-8x+14=2x-7
Add 8x to both sides.
x^2+14=10x-7
Add 7 to both sides.
x^2+21=10x
x^2+7*3=10x
(x*7)+(x*3)=10x
x=7,3
Hope this helps plz hit the crown :D
