5 0

Step-by-step explanation:

a) 2z+3z+4z=180

9z=180

z=20

So,three angles are 40,60 and 80

b) (y+30)+(2y+80)+(y+10)=180

y+30+2y+80+y+10=180

4y+120=180

4y=60

y=15

Three angles are 45,110,25

KatRina [158]

Answer:

<u>Since the circle covers 360°, each sector will be:</u>

360°/18 = 20°

The same angle will be made between two adjacent semicircles.

The points have same latitude but different longitude.

35°W and 15° are at different sides from zero longitude.

<u>The difference is:</u>

35° + 15° = 50°
