Step-by-step explanation:
Angle XBC = 55 degrees because it is a corresponding angle with Angle AXC
and corresponding angles are equal or congruent.
Ok so angle XBC = 55 degrees and since this an isosceles triangle
XBC = XCB which means XCB = 55 degrees
Now to find angle BXC we know that all angles of a triangle add up to 180 degrees.
Angle XBC + Angle XCB + Angle BXC = 180 degrees
Let x represent angle BXC
55 + 55 + x = 180
110 + x = 180
x = 180 - 110
x = 70
∴ Angle BXC = 70 degrees
Probably the question should say , as is negative for .
In that case, recall that
Because lies in the third quadrant, we expect to also be negative, so we take the negative root above. Then

Answer:
12+27a
Step-by-step explanation:
3(4+9a)=3(4)+3(9a)=12+27a
8.45 = 8 45/100 = 8 9/20 = 169/20
A. 8 3/8 = 67/8
B. 8 4/9 = 76/9
C. 8 3/5 = 43/5
D. 8 5/12 = 101/12
The common denominator of all those fractions is 360, so we can write them as:
8.45 = 3042/360
A. 8 3/8 = 3015/360
B. 8 4/9 = 3040/360
C. 8 3/5 = 3096/360
D. 8 5/12 = 3030/360
As a mixed numbers:
8.45 = 8 162/360
A. 8 3/8 = 8 135/360
B. 8 4/9 = 8 160/360
C. 8 3/5 = 8 216/360
D. 8 5/12 = 8 150/360
Now we can easily see that only 8 216/360 is greater than 8 162/360. It means the correct answer is C: From the given mixed numbers, only 8 3/5 is greater than 8.45.
