Step-by-step explanation:
hi the steps are in the picture attached by me
If we say that side "a" is the shortest (adjacent), side "b" is the second shortest (opposite), and side "c" is the longest (hypotenuse): then angle A would be 30°, angle B would be 60°, and angle C would be 90°
tan B = b/a
or
a tan B = b
they have 4 as the smallest value in all four options, so we know that
a=44 tan 60° = b
tan 60° = √3
so, 4 tan 60° = 4√3
b=4√3that leaves two options left, so now we find "c":
c^2 = (a^2) + (b^2)
OR



so
a=4, b=4√3, and c=8
Making your answer
B
Answer:
X=5
Step-by-step explanation:
Collect like terms then move the terms. Then collect liked terms. Calculate and Chang signs
I would do 12 x 10 = 120
to compensate do 120 - 12 =108 same as 12*9 = 108
The estimate is decent, because we are only $12.00 from the real answer.
