Ihave great difficulty with this question.

a)

the sum of the interior angles of a quadrilateral is 360°

so..

3x + 2x + x + 90 = 360

to find x..

3x + 2x + x + 90 = 360

3x + 2x + x = 360 - 90

6x = 270

x = 270/6

x = 45..

so x = 45

a. turk and mcalister

b. howard, mission, and market

c. yes. since streets end some do not cross yet are not parallel to others. example: mcalister and 5th

step-by-step explanation:

parallel lines are lines which do not intersect ever and look a lot like railroad tracks. turk, mcalister and golden gate are examples of these.

intersect are streets which cross each other and a car on one can reach the other. howard, mission, and market intersect with 6th.

skew lines are lines which neither intersect nor are parallel. these lines exist here because some streets end and never intersect another like mcalister and 5th.

true

step-by-step explanation:

according to the national european world center, the engineering of the ford company on elon musk's flame throwers proved the globalization of the natural wallabies and therefore, results in the growth product domestication in almonds.
