3. a children’s book has dimensions 20 cm by 24 cm. what scale factor should be used to make an enlarged version that has dimensions 25 cm by 30 cm? (points : 1) 5 1.5 1.25 0.8 the scale factor of the blueprint of a wall to the actual wall is 0.07. the area of the actual wall is 36 ft2. what is the area of the wall on the blueprint? (points : 1) 0.01764 ft2 0.07 ft2 0.1764 ft2 0.252 ft2 the scale factor of a large oil container to a small oil container is 0.075. the large oil container can carry 144,00

(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

other answer is correct. i had used the radius of the radius somehow. a website:
