Answer:
(a) a squared + 15 squared = 17 squared
Step-by-step explanation:
The Pythagorean theorem tells you the sum of the squares of the sides is equal to the square of the hypotenuse.
a^2 + 15^2 = 17^2 . . . . . . matches the first choice
I think 5006.2 because you move the decimal place 3 times
Answer:
cos = adjacent of angle A / hypotenuse
Step-by-step explanation:
cos = adjacent of angle A / hypotenuse . . . . . . . . . . . .
Let's say the Height of the triangle is 4 cm., the Base is 3 cm, and the Hypotenuse is 5 cm. If the top angle was angle A then the value would be 4/5. Because the Height is adjacent to angle A and the Hypotenuse is 5 cm.
Area of a square of side x = x^2.
If this area is 100 m^2, 10^2 m^2. The length of one side of this square
is the sqrt of 10^2 m^2, or x=10m.
