DBH make a triangle.
The three inside angles of a triangle need to equal 180
H = 180 - B - D
H = 180 - 39 - 36 = 105
H and X make a straight line that equals 180 degrees
X = 180 - H
X = 180 - 105 = 75 degrees.
206 X .4 = 82.4
That's the answer.
If I’m correct this is supposed to be a decimal ( here we use the dot not the comma ) but if so then 32.52 a good way to remember is 5 or more let it sore (meaning round up) four or less let it rest (meaning it stays the same)
Answer:
b = 15.7 -2a
Step-by-step explanation:
You are asking us to solve for b
2a +b = 15.7
Subtract 2a from each side
2a-2a+b = 15.7 -2a
b = 15.7 -2a
Your answer is c lmk if I’m wrong
