Angle of fire in degrees = 90 + 30 =120 degrees
Angle of fire radians =180 degrees = π
120* π/180=120π /180 OR 4π/6 OR 2π/3
15 inches long add 7+5 to get the full total of miles
The average speed of Dolly is 33.33kmph.
Average Speed:
The average speed is defined as the total distance travelled by the object in a particular interval of time. It can be calculated by dividing the total distance travelled by the total time taken.
So, Average Speed = total distance / total time
Here,
Let the total distance is 100 km.
Therefore, consider she will travel 60 km at speed of 60 kmph , 30 km at speed of 30 kmph and 10 km at speed of 10 kmph.
she will required times of 1 hour, 1hour and 1hour
So,
Average speed = 100 / (1 + 1 + 1)
=> 100 / 3 = 33.33

Explanation:
The three Reasons tell you what to look for to put in the Statement blank.
1. We are given that RE = 2AR and RT = 2GR.
2. The only vertical angles in the figure are ...
∠GRA ≅ ∠TRE
3. Using the given relation between the sides, we can write the proportion ...
RE/RA = RT/RG = 2
It is nice, though maybe not absolutely essential, to write the segment names in order of corresponding vertices.
4. Having shown that two sides are proportional and the angle between them is congruent, we can claim similarity using the SAS Theorem.
X is 15because 15-10=5
x= 3*5
x=15
