Chapter 8: Q. 7 (page 555)

In Problems 6鈥�8, solve each triangle.

a=3,b=7,A=40掳

Short Answer

Expert verified

We can't solve the triangle because there is no triangle.

Step by step solution

01

Step 1. Given Information 

The given sides area=3andb=7.The given triangle is40掳.We have to solve the triangle.

02

Step 2. Solve

As we have given the two sides of the triangle and an angle. Therefore, the triangle is SSA triangle.

To solve the traingle we use the law of sines formula sinAa=sinBb

Substitute the values in the formula

sin40掳3=sinB70.214掳=sinB71.49掳=sinB

As we know that the angle of sine can't be more than one.

Thus, there is no triangle.
