R^2+(ab)^2= (ao)^2
ab=6
ao=11.7

Plug in

r^2+6^2=11.7^2

simplify

r^2+36= 136.89
-36 both sides

r^2=100.89
square root both sides

r= 10.04 rounded 10

A construction company wants to build an auditorium on a trapezium shaped plot measuring 410m2. One of the parallel sides of the

Assoli18 [71]

Answer:

other parallel side is 23m

Step-by-step explanation:

Let's assume other parallel sides as 'x'

One of the parallel sides of the trapezium plot measure 18m

so, y=18

distance between the two parallel sides measure 20m

so, h=20

now, we can use area of trapezium formula

$A=\frac{1}{2}\times h \times (x+y)$

now, we can plug values

$A=\frac{1}{2}\times 20 \times (x+18)$

we can set A=410

and then we can solve for x

$410=\frac{1}{2}\times 20 \times (x+18)$

$10\left(x+18\right)=410$

$x+18=41$

$x=23$

You are given the equation \sqrt{76+n } and \sqrt{2n + 26}. What is the smallest value of n that will make each number rational?

Diano4ka-milaya [45]

Answer:

A proof that square root of 2 is irrational. ... An equation x² = a, and the principal square root ... The number under the radical sign is called the radicand. ... the given square numbers, each product of square numbers is equal to what square ... are relatively prime -- and it will be impossible to divide n· n into m· m and get 2.
