Not Here

C x = 28°

Step-by-step explanation:

(x +30)° + (3x +10)° + x° = 180°

x +30 + 3x + 10 + x = 180

5x + 40 = 180

5x = 140

x = 28°

the answer is 0.3175 hope that you ^w^

also you might actually want to put this picture up if you want people to solve it luckily i remember this question

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
