Answer:
yes
Step-by-step explanation:
You can check to see if the numbers satisfy the Pythagorean theorem.
9² +12² ?= 15²
81 + 144 = 225 . . . . yes these segments form a right triangle
_____
You know that segments of lengths 3, 4, 5 form a right triangle. This is the first "Pythagorean triple" that most folks run across. The segments given here are all 3 times those numbers, so will also form a right triangle.
Answer:
In terms of π, the area of the shaded sector is 108πin²
Step-by-step explanation:
Area of the shaded sector, which is the major sector=x°/360(πr²)
A=270/360×π×(12in)²
A=¾π×144in²
A=108πin²( in terms of π)
Answer:
y = 2
Step-by-step explanation:
For the equation x - y = -1, if x = 1,
then we would plug that in to solve for the y value
1 - y = -1
Subtract 1 from both sides to find y
-y = - 2
Divide by -1 to find y
y = 2.
To double check our answer we would plug in our x-value and y-value into the equation
1 - 2 = -1
This is true, so our answer is y = 2
