The absolute value of -81 has the same absolute value as that of 81 because they both have the same distance to 0.
Answer:
2 sqrt(5) =x
Step-by-step explanation:
We can use the Pythagorean theorem since this is a right triangle
a^2 + b^2 = c^2
2^2 +4^2 = x^2
4+16 = x^2
20 = x^2
Take the square root of each side
sqrt(20) = sqrt(x^2)
sqrt(4*5) = x
sqrt(4) sqrt(5) =x
2 sqrt(5) =x
Answer:
Astronomers directly use geometry in their work rather than accountants , judges, pharmacist and politicians.
They used geometry to measure velocity , direction, distance, relativity, momentum, and probability. They used it to look at objects in the sky with a telescope by setting a required angle to get a proper view .
But Accountants, judges, pharmacist and politicians are not in use of geometry directly or frequently.
Hence, Option 'B' is correct.
Step-by-step explanation:
Answer:
QS = 38
Step-by-step explanation:
First, we need to find the value of x.
Given that R is the midpoint of Q and S, that means QR = RS.
6x-11 = 2x+9
Solve.
x = 5.
To find QS, we need to solve the following equation:
6x-11 + 2x+9
Substitute 5 for x.
6(5)-11+2(5)+9
30-11+10+9
38
