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°
Ok. Could I have a picture of the question? :)

Answer:
y= 3x − 4
Step-by-step explanation:
The slope-intercept form for a linear equation is
y= mx + b, where m = the slope, and b = the y-intercept.
Given:
m= 3 and b = −4
y= 3x - 4
