Answer:
A≈676.2
Step-by-step explanation:
1. Exponentially solve equation
A=249e-0.0015t as t = 43 years (Unless conversion to seconds)
A≈676.2
2. Solve graphically = intersect = (43, 676.2) x axis is time y axis is amount.
A + 3A = 120
4A = 120
A = 30
B = 90
Answer:
Area= 50√3 units^2
Step-by-step explanation:
Given:
In given triangle, there are two sides with length 10√3 and 20 along with angle of 30° between them.
As the given triangle is SAS triangle, we'll use the following formula to calculate its area:
A=1/2absinC
where a= 20
b= 10√3
and c=30°
Now putting values we get:
A=(1/2)(20)(10√3) sin(30)
=100√3(1/2)
=50√3
so the area is 50√3 units^2 !


__________________________________________

- BCD is an isosceles right triangle , right angled at D
- ABC is an equilateral triangle


❒ Sum of all angles is 180° , since it is an equilateral triangle all the three angles would be same





(Isosceles triangle)
