please help. how do i find these angles and what are they? if you can pls explain the angles too. thank you so so much !!

5. 1=112º

5. 2=68º

5. 3=112º

6. 1=45º

6. 2=45º

6. 3=135º

Step-by-step explanation:

5. 1 is a vertical angle to 112º, so they are equal (1 is obtuse)

5. 2 and 112º form to create a straight angle (line/180º) (supplementary angles) so subtracting the known number (112) from the total (180) gives you the number of the missing angle (2 is acute)

5. 3 is the same as 1 (3 is obtuse)

6. 1 and 45º are equal to each other (1 is acute)

6. 2 and 1 and 45º are equal and vertical angles (2 is acute)

6. 3 and 45º form to create a straight angle (line/180º) (supplementary angles) so subtracting the known number (45) from the total (180) gives you the number of the missing angle (3 is obtuse)

180

step-by-step explanation:

10.416 meters per second

step-by-step explanation:

distance=1 00 meters

time= 9.6 seconds in decimal form or 9 3/5 as a mixed number

average speed= 100/9.6

=10.416 meters per second or 10 52/125 as a mixed number.
