Answer:
x = 87
Step-by-step explanation:
An exterior angle of a triangle is equal to the sum of the opposite interior angles.
Label the angles left and right of the right angle as "a" and "b". Then we have ...
a + b + 90 = 180
b = 90 - a . . . . subtract (90+a)
And we have a relation with the left exterior angle:
72 + a = 138
a = 138 -72 = 66 . . . . subtract 72
__
b = 90 -66 = 24 . . . . from above
And another relation with the right exterior angle:
(180 -x) +b = 117 . . . . . . the interior angle with "b" is the supplement of x
204 -x = 117 . . . . . . . . . substitute 24 for b
204 -117 = x = 87 . . . . add x-117
The measure of the angle marked x° is 87°.
Answer: 3.65
Step-by-step explanation:
This question is asking basically what is 50% or 1/2 of 7.3.
Let's expand the number 7.3
Then, we end up getting 7.30.
We have to find 1/2 of 7.30.
of 7.30 =

Answer:
C
Step-by-step explanation:
120 *.3 = 36
120-36 = 84
84*.3 = 25.2
84-25.2= 59.8
120*.6 = 72
120-72 = 48
59.8-48 = 10.8 C
