Answer: 3cm
Explanation:
We can use Pythagorean’s theorem to find that other side:
a^2 + b^2 = c^2
a^2 + 4^2 = 5^2
a^2 = 25 - 16
a^2 = 9
a = 3
Therefore, the other side is 3cm
The correct answer is the One fired from from 60° . This is because the projectile fired from 60° has a greater vertical velocity compared to the one fired from 30° and therefore spends more time on air. Vertical velocity is the velocity of a body as it moves upwards, it is normally affected by the gravitational acceleration, however it is not affected by the horizontal velocity.
Answer:
The factors of 91 by prime factorization are 1, 7, 13 and 91. Here, 7, and 13 are the prime factors of 91.
Step-by-step explanation:
Answer: a 180° rotation about its center
Step-by-step explanation:
<em>A parallelogram has rotational symmetry of order 2.</em>
Thus, rotation transformation maps a parallelogram onto itself 2 times during a rotation of 
about its center.
And that is at 
and about its center.
Therefore, a 180° rotation about its center will always map a parallelogram onto itself .
- A figure has<em> rotational symmetry </em>when it can be rotated and it still appears exactly the same.
- The<em> order of rotational symmetry</em> of a shape is the number of times it can be rotated around and still appear the same.
