The given inequality is
First we need to remove the absolute sign , and when we do so , we will get a compound inequality, that is
To solve for x, first we need to get rid of 10. and for that, we have to do subtraction
Now we need to get rid of 9, and for that, we do division
So the required solution is
Answer:
A variable
Step-by-step explanation:
I figure you are asking for the vocab word, but if not, then it could be x and y.
Part a: The value of x is 33°
Part b: The measure of each base angle is 69°
Explanation:
It is given that the vertex angle of an isosceles triangle measures 42°.
The base angle in the triangle has a measure of
Part a: To determine the value of x
Since, in an isosceles triangle the base angles are always equal.
Thus, the three angles in an isosceles triangle add up to 180°
Hence, we have,
Thus, the value of x is 33°
Part b: To find the measure of each base angle.
Base angle =
Substituting , we get,
Thus, the measure of each base angle is 69°
