Answer:
42.3
Step-by-step explanation:
add both angles then subtract by 180 and the negative number is your answer
Answer:
all of them except straight and reflex
Step-by-step explanation:
when angles are supplementary it means that they add up to 180
an acute angle is supplementary to an obtuse angle
an obtuse angle is supplementary to an acute angle
a right angle is supplementary to a right angle
but a reflex angle is over 180 so it's not supplementary to anything
and a straight angle is already 180 so it has no supplements either
Answer:
D. 65 degrees
Step-by-step explanation:
If two sides are congruent the corresponding angles are also congruent
Answer:
b equals 20
Step-by-step explanation:
b - 13 = 7
7 + 13 = b
7 + 13 = 20
Answer:
log(32/125)
=log32 - log125 [log(x/y)=log(x) - log(y)]
=log(2)^2 - log(5)^3
=2log2-3log5 [log(x)^p=p log x]
=2a-3b
