Answer:
D
Step-by-step explanation:
Well, since t = time in air, we already know that it traveled 2 seconds.
H = height in meters, and H = 18
So, after 2 seconds the object is 18m in the air
So, option D
Answer:
6
Step-by-step explanation:
43-7=36
The square of 36 is 6.
Step-by-step explanation:
BC = AD (opposite sides in parallelogram is equal)
x + 8 = 2x + 1
8 - 1 = 2x - x
7 = x
x = 7
BC = x + 8 = 7 + 8 = 15
Answer:
Two triangles are similar if they have: all their angles equal; corresponding sides are in the same ratio; But we don't need to know all three sides and all three angles ...two or three out of the six is usually enough. There are three ways to find if two triangles are similar: AA, SAS and SSS: AA
Step-by-step explanation:
Finding the perimeter of a shape is just adding up the length of the sides. the vertical sides are 4 + 6, which is 10. For the hypotenuse, use Pythagorean Theorem. 4² + 6² = 16 + 36 = 52. Take the square root of 52: 7.211, and add it to 10. This makes the perimeter 17.211 units.
