What does a equal? (b = 3√2)

9514 1404 393

  a = √2

Step-by-step explanation:

Triangle EFG is an isosceles right triangle, so the ratios of side lengths are ...

  1 : 1 : √2

That is, we have ...

  3a/6 = 1/√2

Multiplying by 2 gives ...

  a = 2/√2

  a = √2

(2x + 16) + (x) = 180

step-by-step explanation:

given,

abcd is a quadrilateral inscribed in a circle

angle a is labeled x plus 16, (x + 16)

angle b is labeled x degrees, (x)

angle c is labeled 6x minus 4, (6x – 4)

angle d is labeled 2x plus 16, (2x + 16)

what equation can be used to solve for angle b?

we know that the sum of the opposite angles of a simple quadrilateral inscribed in a circle is 180 degrees.

angle b is opposite angle d

therefore, angle b + angle d = 180

(x) + (2x + 16) = 180 

same as (2x + 16) + (x) = 180
