Answer:
m<DBC=120°
Step-by-step explanation:
2x+x+90=180
3x=180-90
3x=90
x=30
m<DBC=x+90=30+90=120
The word equiangular means that all the angles of the figure are equal. Further, equilateral means that all the measures of its sides are also equal. From the given above, only a square is both equiangular and equilateral. Thus, the answer is letter B.

5xy^5 because 10/2=5 then remove the y^8 then collect like terms which leaves u with 5xy^5
Answer:
30 years old.
Step-by-step explanation:
Here's what we know.
B=5J
M+2=8J+16
M=3B
So now let's solve using substitution.
M+2=8J+16
M=8J+14
But we know that M=3B
3B=8J+14
And we know B=5J
3*5J=8J+14
15J=8J+14
7J=14
J=2
Now, we can plug it into the M+2=8J+16
M+2=2*8 +16
M+2=16+16
M+2=32
M=30
