Answer:

The measure of angle 1 is 78 degrees.

Step-by-step explanation:

A straight line has an angle of 180 degrees. We are assuming this is a straight line, meaning angle 1 and angle 2 together should add up 180 degrees. If the measure of angle 2 is 102, the measure of angle 1 should be supplementary, which is another mathematical way of saying it adds up to 180 degrees. The measure of angle 1 has to be 78 degrees to make the angles add up to 180 degrees.

=> 875

Workout gym

=> membership fee = $200

=> monthly fee = $45

=> First month = 245$

=> 200 + 45(x)

6 and half minus seven-eighths divided by five and eleven-sixteenth=
kow [346]
The answer is 90/91. 6 1/2 - 7/8 divided by 5 11/16. Turn 6 1/2 and 5 11/16 to an improper fraction. 6 1/2= 13/2. 5/11= 91/16. Then you have to get each fraction to have equal denominators. All of them can have a denominator of 16. So you times everything to get a denominator of 16. 13/2= 104/16. 7/8=14/16. 91/16 stays the same because the denominator is already 16. Next you subtract 104/16 and 14/16 and get 45/8.( because you need to put it in simplest form.) Lastly you divide 45/8 by 91/16 and get 90/91.
