Help, please, please!!

Answer 1

The answer to your question is 65

Answer 2

Explanation:

The sum of the angles in a triangle is always 180 degrees.

40+3x+180-5x+10=180

-2x+50=0

-2x=-50

x=25

Again using the fact that the angles must have a sum of 180

40+3x+a=180

40+3(25)+a=180

40+75+a=180

a+115=180

a=65

So angle 1 is 65 degrees.
