Answer 2

Answer:

$\rightarrow \sf \: false \\ \rightarrow \sf \: true \\ \rightarrow \sf \: true \\ \rightarrow \sf true \\ \rightarrow \sf \: false \\ \rightarrow \sf \: false$

Step-by-step explanation:

1) No, because the total measure of triangle is 180⁰ and if we take two angle as right angle than it is 90⁰+90⁰ = 180⁰ . so, third angle is not their . So, it is false.

5) No, because for ex. we take angle like 91, 95,85 these all are abtuse so, if we add them than it measures 351⁰ it is more than 180⁰ .
