Area of a triangle with a= 60 degrees, b=11 and c=8 feet round to the nearest tenth

The area of the triangle is  38.1 ft^{2}

Step-by-step explanation:

we know that

The area of a triangle is equal to

Applying the law of sines

A=(1/2)(b)(c)sin(A)

substitute the values

A=(1/2)(11)(8)sin(60°)=38.1 ft^{2}

it’s supposed to be -4+45=41

step-by-step explanation:

correct choice is b

step-by-step explanation:

when you calculate the average rate of change of a function, you are finding the slope of the secant line between the two points. for the function the average rate of change from point to point can be calculated as

to find the average rate of change from day 2 to day 10, note that at day 2, 8 houses were sold, so a(2,8) and at day 10, 2 houses were sold, so b(10,2). thus,
