Which side of angle measures could be the interior angles of a triangle?
jok3333 [9.3K]

The sum of all the angles of a triangle is 180 degrees.

If you add 90 + 90 + 90 together you get 270. These can not be the angle measures of interior angles of a triangle because the sum is more then 180.

If you add 80 + 80 + 200 together you get 360. These can not be the angle measures of interior angles of a triangle because the sum is more then 180.

If you add 40 + 50 + 60 together you get 150. These can not be the angle measures of interior angles of a triangle because the sum is less then 180.

If you add 15 +30 + 135 together you get 180! This set of angle measures can the be interior angles of a triangle!

Hope this helped!

2. Dilute hydrochloric acid reacts with zinc to form zinc chloride and hydrogen.
DIA [1.3K]

Step-by-step explanation:

Zn + 2HCl => ZnCl2 + H2

Moles of Zn = 13g / (65.38g/mol) = 0.198mol

Volume of HCl = 0.396mol / (0.25mol/dm³) = 1.58dm³.

Volume of H2 = 0.198mol * (22.4dm³/mol) = 4.43dm³.
