An artist is working on the design of a logo for the T-shirts that the participants in the walk will receive. He starts by drawing ∠ADC so that it measures 60°. Next, he draws DB so that m∠BDC is 10° greater than m∠ADB. c. What postulate did you make use of to answer parts a and b? How did this postulate help you write an equation that could be solved for x?

x = 2

step-by-step explanation:

if sr parallel to ba then the sides bc and ac are in proportion, that is

= ← substitute values

= ( cross- multiply )

27x = 6(4x + 1)

27x = 24x + 6 ( subtract 24x from both sides )

3x = 6 ( divide both sides by 3 )

x = 2

no because mercury has a density of 13.6 grams per centimeter squared while gold has 19.32 grams centimeter squared
