60°

Step-by-step explanation:

Because of the rule that all triangle's angles must measure to 180°.

So I did...

60+60=120

180-120= 60

Answer

60 degrees

Step-by-step explanation:

A triangle is 180 degrees. So if you add both 60 degrees it would equal 120, substracted by 180 and you'll get 180. Or if you want to go the faster way, remember that a triangle will equal 180.

the answer is 510

step-by-step explanation:

15 • 13 = 195

15 • 12 = 180

15 • 5 = 75

12 • 5 = 60

195 + 180 = 375

375 + 75 = 450

450 + 60 = 510
