I don’t understand what I have to do

over 90° = obtuse angle

less than 90° = acute angle

two angles next to eachother on the same flat line are a+b=180

so angle 1 is 180-135=45

There are different types of angles. They are as follows:

1) Acute angle - less than 90 degrees

2) Right angle - exactly 90 degrees

3) Obtuse angle - greater than 90 degrees but less than 180 degrees

4) Straight angle - exactly 180 degrees

5) Reflex angle - greater than 180 degrees

In part 1 they want you to identify what kind of angle is shown

Number 1 is 135 degrees

-It is not less than 90 degrees so it cannot be an Acute angle

-It is not exactly 90 degrees so it cannot be a Right angle

-It is not exactly 180 degrees so it cannot be a Straight angle

-It is not greater than 180 degrees so it cannot be a Reflex angle

-It is greater than 90 degrees and less than 180 degrees so it is in fact an Obtuse angle

For part 2 they want you to calculate the value of the missing angle

A straight line has 180 degrees so we can find the value of the missing angle by subtracting  135 degrees from 180 degrees

180 - 135 = 45

The missing angle is 45 degrees which is an Acute angle because it is less than 90 degrees

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.

i believe that the slope of the line is -5
