It is Associative Property
4•4 -1•1 = 16-1 = 15 square inches
1/2 (2) + 3 + 5.3 (3)
1 + 3 + 15.9
19.9
C i believe because 180 is the overall degree and 50+28=78 and 180-78=102
Answer:
38 degrees
Step-by-step explanation:
this is an isosceles triangle, meaning that the base angles are congruent.
the total triangle is equal to 180
so the equation would be: x=180 - (71+71)
evaluate:
x=180-142
x=38 degrees
Hope this helps :)
