The difference (-) between 3 times a number (3n) and 21.
3n - 21
Answer:
11,5 cm or 23 squares
Step-by-step explanation:
draw a cartesian graph and put on the coordinates given then use a ruler
We have that the value of x in the diagram at the right is
x=109
From the question we are told
Use this idea to find the value of x in the diagram at right.
From The diagram we have a Triangle with its base angles equal
Generally the equation for the Triangle is mathematically given as
180=2b+y
Where
b=Base angles
Since Angle on a straight line is 90
Therefore
180=71+x
x=109
In conclusion
The value of x in the diagram at the right is
x=109
