The vertex angle of an isosceles triangle measures 42°. a base angle in the triangle has a measure given by (2x + 3)°. what is the value of x? what is the measure of each base angle?

x=33

Each base angle measures 69 degrees

Step-by-step explanation:

the 2  base angles are equal so  the measure of 1 base angle = (180 - 42) / 2

=  69 degrees

2x + 3 = 69

2x = 66

x = 33

in the attachment.   i didn't see your choices.   the word which means there is choices.

step-by-step explanation:

(x,y)

x tells you how much left or right you go from the origin

y tells you how much down or up you go from the origin

so for example (-3,2), you go left 3 and up twice. i denoted which of the ordered pairs is which in my graph.
