Simple...plug n chug..
3x-4(4)=65
3x-16=65
Now, isolate the variable, x....
3x-16=65
+16 +16
3x=81
Now, divide,
x=27.
Thus, your answer.
Ответ:
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°
