Geometric mean of two numbers is squre root of thir product.
Given numbers are 12,20
Geometric mean = √(12*20)
= √240
= 15.49
= 15.5

Answer: Find the value of X in triangles by subtracting known angle measurements from 180 degrees. Since the value of all angles within a triangle must equal 180 degrees, if you know at least two angles, you can subtract them from 180 to find the missing third angle
Step-by-step explanation:
Answer:
17.43 = 2.49x equation
answer: 7
Step-by-step explanation:
17.43 = 2.49x
First divide 2.49 by 17.43
17.43/2.49
which will give you the result of
7
Answer:B
Step-by-step explanation:
If the air is colder than the water you would have -2-9 because if you keep,Change and flip it it it is -2+-9 which is -11.
Answer:
In this case, you can use the concept of cosine to calculate y, and things are even easier when you have one of the special angles which is a 45° angle.
So we know that: cos45° = √2/2
This fact will always be true. In our case, we have:
cos45° = 7/y
Therefore, we have the equation:
7/y = √2/2
⇔ 14 = y√2
⇔ y = 14/√2
⇔ y = √196/√2 = √(196/2) = √98 = 7√2
So y is equal to 7√2
