Answer:

<ABC = 68degrees

Step-by-step explanation:

From the diagram, the measure of the given angles are supplementary;

9x+5 + 16x = 180

25x = 180 - 5

25x = 175

x = 175/25

x = 7

<ABC = 9x +5

<ABC = 9(7)+5

<ABC = 63 + 5

<ABC = 68degrees

The ratio of the length of two similar re rectangles is 3 ratio 4. what is the scale ratio of their areas in
Effectus [21]

Answer:

9:16

Step-by-step explanation:

The ratio of sides of the lengths of rectangles is 3:4.

  • Now since the scale is constant. So the scale ratio of area will be square of the side ratio .

<u>T</u><u>hat </u><u>is </u><u>:</u><u>-</u><u> </u>

→ Ratio of Area = ( 3 : 4)²

→ Ratio of Area = (3/4)²

→ Ratio of Area = 9/16

→ Ratio of Area = 9:16

<h3>Hence the ratio of areas is 9:16 .</h3>
