this is due to effect of sin2(theta). as sin2(theta) will repeat its value for =90-theta
as here
theta=30 so
for 90-30=60
sin2(30)=sin2(60)
so for pair of projection angles of two projectiles as(theta,90-theta) , they will have same ranges
i.e
theta=10
and 90-10=80
sin2(10)=sin2(80)
At 30 degrees and 60 degrees, the sine values are equal. Since the range of a projectile depends on the initial vertical velocity (which is influenced by the sine of the launch angle), the ranges are equal at these angles as the vertical component of the initial velocity remains the same.

What degree of latitude consists of 60 equal parts?
One degree of latitude is divided into 60 minutes. Each minute is further divided into 60 seconds.
How many quarts equal 60 pints?
There are 30 quarts in 60 pints. This is because 1 quart is equal to 2 pints, so to convert pints to quarts, you divide by 2.
How is a drgree of longitude or latitude further subdivided?
Each degree is divided into 60 minutes, and each minute is divided into 60 seconds. While the distance represented by a degree of longitude can vary with the latitude, each degree of latitude (north and south) is equal to 60 nautical miles, so one minute of latitude is equal to 1 nautical mile. (About 1.15 statute miles) One nautical mile is equal to 2026 yards, so one second of latitude is equal to 33.8 feet.
How much is 60 degrees in NM?
60 degrees is equivalent to 1,852,000 nanometers (nm), since 1 degree is approximately equal to 30,866,666.7 nm.
What is each degree of latitude or longitude further subdivided into?
Minutes (1/60 of a degree) and seconds (1/60 of a minutes). After that you use decimals of a second.
Water is projected from two rubber pipes at the same speed-from one at an angle of 30 and from the other at 60why are the ranges equal?
w2hen the angle of projection is larger than 45 degree the height attained will be more but the range is again less.in this case angle is 30 degree which is less than 45 degree and 60 degree angle is greater than angle of 45 degree which have less range and is equal to range of 30 degree .so ranges are equal.
Why the range is same when projected at the angel of 30 and 60?
water is projected from two rubber pipes at the same speed from one at angle of 30 and from the other at 60 why are the ranges equal
How many degrees is equal to 60 minutes?
One Degree has 60 minutes. 130 minutes are ?1 Degree 30 minutes13 Degrees2 Degrees 30 minutes2 Degrees 10 minutes
What kind of triangle has one 30 degree angle and one 60 degree angle?
A right triangle because all triangles equal 180 degrees. 180-60=120 120-30=90
How is a 30 degree angle related to a 60 degree anlge?
a 60 degree angle is twice the size of a 30 degree angle.
What is 60 - 90 equal?
60 - 90 equal = -30
What is -30 plus 60?
-30 plus 60 = 30
One degree longitude is equal to how many miles?
60 60 60
What is 30 out of 60 as a percentage?
30 out of 60 = 1/2 which is equal to 50%
Is a 30 degree and a 60 degree angle congruent?
yes
What is the 30 degree to 60 degree right triangle theorem?
90
What is the complement of an angle with a measure of 30 degree?
a 60-degree angle
