Answer:
B). 5+c
Step-by-step explanation:
we need to distribute -5-c to -1
we can do it as its written or we can flip it around and still get the same answer. When we distribute we multiply the varable or number out parenthesis with the ones in the paretesis
so -5 *-1=5
-c*-1=c
these two are positive now so they are no longer being subtracted from each other...
your answer is
B). 5+c
second one is correct
Step-by-step explanation:
The sum of interior angles of a triangle must add up to 180 degrees
if the triangle has an angle that is greater than 90 degrees, then it is considered obtuse
if the triangle has an angle that is 90 degrees, then it is considered right
if all angles are less than 90, then it is acute
find the missing angle "x"
180=60+80+x
is angle x less than, greater, or equal to 90 degrees?
