The symbol √ means "square root of". √16 means "square root of 16".
It's a number that gives 16 when you multiply the number by itself.
There are <u>two</u> numbers that can both do the job. They are +4 and -4.
(+4) times (+4) = 16
(-4) times (-4) = 16
C=√a²+b. square both sides
c²=a²+b². subtract a² from both sides
c²-a² = b². take the square root of both sides
b=±√c²-a²
but since length can never be negative we consider only the positive root
b=√c²- a²
Answer: sry
Step-by-step explanation:
8 because only the green marbles got added
Answer:
The last one, angle D equals to angle T
Step-by-step explanation:
Using the theorem of the triangle we know that the total number measure of the angles is 180 degrees. Therefore, solving the second triangle will give us that the angle T is equal to 60.
This is equal to angle D.
Hope this helps.
