Find the area of the triangle. If necessary round the answer to decimal places x=20 degrees b=11 c=5

Step-by-step explanation:

Given

See attachment for triangle

Required

Calculate the area

The area is calculated as:

In this case, it is:

So, we have:

1. isolate the variable, in this case, d. subtract 35.5 on both sides of the equation.2. 52 subtracted by 35.5 is 16.53. therefore your answer would be d= 16.5this is the basics of pre algebra, isolating variable through adding, subtracting, multiplying, and dividing, if you have any other questions to ask just comment!
