Answer:
15degrees
Step-by-step explanation:
From the given diagram
<1+<2 + <DCB = 180
<1+<2+120 = 180
<1+<2 = 180 - 120
<1+<2 = 60
<2 = 60 - <1
<2 = 60 - 45
<2 = 15degrees
Hence the measure <2 is 15degree
14
11 - n = -3
-n = -3 - 11 = -14
n = 14
OR
add n to both sides of equation and add 3 to both sides of equation:
11 - n + n + 3 = -3 + n + 3 ----> n = 14
x=7.2 y=7.5 this is the answer
ok
9+10=21
