A painting is 11.5 cm wide and 18 cm tall. If it is reduced to a width of 4.6 cm, then how tall will it be?

7.2 cm

Step-by-step explanation:

First you want to divide 11.5 and 4.6. Which is 2.5. Then divide 18 by 2.5 because you want to do the same to both numbers. Which is 7.2 cm.

45 cm

Step-by-step explanation:

A = 11.5 × 18 = 207 cm²

h = A ÷ 4.6

h = 45 cm

the sum of all the angles in a triangle are equal to 180

so you can add   the 3 given angles together to equal 180:

5y + 2y + 2y = 180

or since all three angles have the same letter, combine the 3 angles to equal 180:

9y = 180
