Answer:
see explanation
Step-by-step explanation:
(1)
The sum of the 3 angles in a triangle = 180° , thus
a + b + c = 180
(2)
adjacent angles are supplementary, thus
b + d = 180
(3)
From (1) and (2)
b + d = a + b + c ( subtract b from both sides )
d = a + c
Answer: B and C
Step-by-step explanation:
-3/5 + u = 1/2
To find u , you have to shift all the “numbers” to one side
u = 1/2 + 3/5 = 11/10
( note that when -3/5 moves to the other side , the sign changes and become positive “ + “ )
Hope this helps!
