If a triangle has angle measurements of 25∘ and 40∘, what is the measure of the third side?

Step-by-step explanation:

Let the third angle be x

Sum of all the angles of a triangle = 180°

25 + 40 + x = 180

65 + x = 180

x = 180 - 65

x = 115°

step-by-step explanation:

ok so im not 100% sure but you would start by adding 5.1t and 1.9t beacuse they have the same variable. that is 7t.   then add -3.6 + 1.2 which is -2.4

so then keep that as -2.4 + 7t. i apologize if this is incorrect. best luck on your test < 3
