Answer:

1. 2

2. -9

3. 2+-9

4. -7

5. -15 + 8 = -7

Step-by-step explanation:

The surface of the water is 0. If Paula is above the surface of the water than she is positive. If she is below or heading down she is negative. She starts 2 feet above which is 2. She descends a total of -9 from 2 to -7. She ends up -7 or 7 feet below surface. So she travels from 2+-9 = -7.

Yolanda owes her friend $15  or -15. She earns $8 a week or +8. If she earns 8 dollars this week and pays Yolanda back then -15+8=-7. She now owes $7.

Question:
alexandr1967 [171]

Answer:

Part 1) The draw in the attached figure

Part 2) m\angle ABD=50^o

Step-by-step explanation:

Part 1)  Draw the described circle

The draw in the attached figure

Part 2) What is the measure of angle ABD

step 1

Find the measure of arc AD

Remember that

arc\ AD+arc\ DC+arc\ AC=360^o ----> by complete circle

substitute the given values

arc\ AD+124^o+68^o=360^o

arc\ AD=360^o-192^o=168^o

step 2

Find the measure of angle ABD

we know that

The measurement of the external angle is the half-difference of the arches that comprise

In this problem

The measure of angle ABD is an external angle

so

m\angle ABD=\frac{1}{2} [arc\ AD-arc\ AC]

substitute the given values

m\angle ABD=\frac{1}{2} [168^o-68^o]=50^o
