Answer:
x+6
Step-by-step explanation:
The given expression is (2+x)+4.
The associative property is :
(a+b)+c= a+(b+c)
Here,
a = 2, b = x and c = 4
So,
(2+x)+4 = 2+(x+4)
= x+6
So, the equivalent expression is x+6.
Answer:
37°
Step-by-step explanation:
By definition all internal angles of a triangle add up to 180°
Hence,
98° + 45° + x = 180°
x = 180° - 98° - 45° = 37°
