Find the area of the triangle abc given angle a = 45°, b = 8, and c = √2. 4 4√2 8 8√2

Area  = 4 units²

Step-by-step explanation:

We have given that

Angle A  = 45° , b = 8 and c = √2

We have to calculate the area of the triangle.

The formula to calculate the area is :

A  =  1/2×b×c×sin(A)

Putting values in above formula, we have

A  =  1/2×8×√2 × sin(45)

A  =  1/2×8×√2×1/√2

A  = 4 units² which is the answer.

the correct answer is 1: 2

solution:

the given function is ,

      =

the three roots of this quadratic function is , 0 ,8 and 10.all the roots are real and rational.

if a quadratic equation is of the form ,

sum of the roots = a + b +c= 0+8+10=18=  

product of roots taken two at a time = a b + b c+ c a = 0+80+0=80 =  

product of roots = a b c = 0=  

there are 11 doors in a hall starting from 0 to 11.the entry in the hall is permitted through gate number 0 and exit is allowed through only gate number 8 and 10.so, three roots(0,8,10) of quadratic function is given by entry and exit route of this hall.
