Answer:

Angle DCA = Angle CAB. (Alternate Interior Angle)

Angle DCA = 68°

Angles(DCA + ACB + BCE) = 180°. (Linear Pair)

Angle ACB + 68° + 33° = 180°

Angle ACB = 79°

Therefore,

Angle ABC = 33°. (Alternate Interior Angle)

Evaluate a−3.45+b for:<br> a=2.88 and b=6.02
Kryger [21]

Answer:

a−3.45+b = 5.45

Step-by-step explanation:

We replace a=2.88 and b=6.02 into a−3.45+b

So we have a−3.45+b = 2.88 - 3.45 +6. 02 = (2.88+6.02) - 3.45=

= 8.90-3.45 = 5.45

The answer is a−3.45+b = 5.45

Have a good day.

15.What is the area of the segment?
Strike441 [17]

Answer:

The Area of a Segment is the area of a sector minus the triangular piece (shown in light blue here). There is a lengthy reason, but the result is a slight modification of the Sector formula: Area of Segment = θ − sin(θ) 2 × r2 (when θ is in radians) Area of Segment = ( θ × π 360 − sin(θ)2 ) × r2 (when θ is in degrees)

FromTheMoon [43]
The ratio being 1:5:3, you would have to just make those numbers still in that ratio, but they have to add up to 180 degrees.The angles would be 20 degrees, 100 degrees, and 60 degrees.  Hope that helped. :)
