3. Find the measure of each base angle in the figure below
A. 62
B. 28
C. 56
D. 124

Answer:
B
Step-by-step explanation:
Every triangle has 180 degrees.
so minus 124 you get 56. So you have 2 more angles so you divide that by 2 to get 28
Both angles are sam as per isosceles triangle .
Let both be x
ATQ
[tex]\\ \sf\longmapsto 124+x+x=180[/tex]
[tex]\\ \sf\longmapsto 2x+124=180[/tex]
[tex]\\ \sf\longmapsto 2x=56[/tex]
[tex]\\ \sf\longmapsto x=28[/tex]
