Answer: <em>3</em>
Step-by-step explanation:
<em>Take your equation x-1=2</em>
<em>Now put 3 in for x</em>
<em>3-1=2</em>
<em>2=2</em>
<em>x=3</em>
Answer:
2/3
Step-by-step explanation:
Answer:
see the procedure
Step-by-step explanation:
we know that
m∠1+m∠2=180° -----> supplementary angles (form a linear pair)
we have
m∠1=27° ----> given problem
substitute the measure of m∠1 in the equation above and solve for m∠2
27°+m∠2=180°
Subtract 27° both sides
27°+m∠2-27°=180°-27° ----> by subtraction property of equality
m∠2=153°
