Step-by-step explanation:
(8 + -9)(9 + -8)
A negative times a positive is a negative.
8 + -9
+- = -
8 - 9
8 - 9 = -1
(-1)(9 + -8)
9 + -8
+- = -
9 - 8
9 - 8 = 1

Answer:
D. m<A = 61°, m<B = 57°, m<C = 61°
Step-by-step explanation:
The sum of all interior angles of a triangle is always equal to 180°.
Therefore, any set of given angle measurement of a triangle should sum up to 180°.
From the options given, the following angle measurements given in option D,
,m<A = 61°, m<B = 57°, m<C = 61° cannot be angle measurements of ∆ABC. This is because they sum up to give 179° instead of 180°.
