180

3. < 1 and < 2 are same-side interior angles. what conclusion can be made about the two angles?

< 1 + < 2 = 90°

< 1 + < 2 = 180°

< 1 = < 2

4. in ∆abc, m

15°

180°

45°

30°

3.<1+<2=180°

Step-by-step explanation:

sun of 2 co interior angle is 180° so..

use substitution to solve each system of equations. y = x + 5 3x + y = 25 62/87,21 y = x + 5 3x + y = 25 substitute x + 5 for y in the second equation. substitute the solution for x into either equation to find y. the solution is (5, 10)

step-by-step explanation:

(d)

step-by-step explanation:

given: the line in the graph passes through points (5,30) and (6,26).

then, the equation of line is:

now, put y=a(n) and x=n,

hence, option d is correct.
