Answer:
A, B
Step-by-step explanation:
The flag has 180° rotational symmetry, so rotation by that amount around the center will map either triangle to the other.
The legs of the triangles are different lengths, so no rotation of 90° or 270° can map one to the other.
The two choices shown below are applicable.
The value of a is 37°, the value of b is 34° and the value of c is 143° in the given triangle.
According to the question,
We have the following information:
We have a triangle with angles given.
We know that angle made on a straight line is 180° and the sum of all three angles of a triangle is 180°.
We also know that vertically opposite angles are equal.
So, a is vertically opposite to 37°.
So, the value of a is 37°.
Now, a and c make a straight line.
c = 180-37
c = 143°
a + b + 109° = 180°
37° + b + 109° = 180°
b+146° = 180°
b = 180-146
b = 34°
Hence, the value of a is 37°, the value of b is 34° and the value of c is 143° in the given triangle.

Because Point Slope Form contains m, or slope, in itself, look at the number that is multiplying the parentheses.
-5/4 is m, or slope.
Part A
(85 km)/(51 min) = (x km)/(60 min)
85/51 = x/60
85*60 = 51x
5100 = 51x
51x = 5100
x = 5100/51
x = 100
<h3>Answer: 100 km</h3>
=====================================================
Part B
510 m = 0.510 km
(85 km)/(51 min) = (0.510 km)/(x min)
85/51 = 0.510/x
85x = 51*0.510
85x = 26.01
x = 26.01/85
x = 0.306
This represents the number of minutes. Multiply by 60 to get the number of seconds
0.306 min = 0.306*60 = 18.36
<h3>Answer: 18.36 seconds</h3>
