If angle ABC is one degree less than three times angle ABD and angle DBC=47 find each measure
Contact [7]

It has not been indicated whether the figure in the questions is a triangle or a quadrilateral. Irrespective of the shape, this can be solved. The two possible shapes and angles have been indicated in the attached image.

Now, from the information given we can infer that there is a line BD that cuts angle ABC in two parts: angle ABD and angle DBC

⇒ Angle ABC = Angle ABD + Angle DBC

Also, we know that angle ABC is 1 degree less than 3 times the angle ABD, and that angle DBC is 47 degree

Let angle ABD be x

⇒ Angle ABC = 3x-1

Also, Angle ABC = Angle ABD + Angle DBC

Substituting the values in the above equations

⇒ 3x-1 = x+47

⇒ 2x = 48

⇒ x = 24

So angle ABD = 24 degree, and angle ABC = 3(24)-1 = 71-1 = 71 degree

The pyrotechnic team for Fist Bump’s tour want to know how high the arena is to 2 decimal places. The arena is 61.3786 metres hi
Aloiza [94]
When you find any value to x amount of decimal places, you need to go to the term AFTER that to determine the correct value.  So, for this, take 61.378 metres.  From here, look if the last number is 4 or less.  If the number is 4 or less, take the leftmost number off, and you will have your answer (if we had 61.373, the correct answer would be 61.37).  If the number is 5 or more, take the leftmost number off, and add 1 to the new leftmost number.  Since the last number is 8, the correct answer here is 61.38 metres high.  If adding 1 makes the number 10, keep the 0 at the end.  So, if you had 61.399, you would make it 61.40
