Answer:
50
Step-by-step explanation:
add 5 to -25 to get -2/5x by itself.
Complentary angles add to 90 degrees
a and b are complentary
a+b=90
a=7x+4
b=4x+9
so
7x+4+4x+9=90
combine like terms
11x+13=90
minus 13 both sides
11x=77
divide both sides by 11
x=7
m a =7x+4=7(7)+4=49+4=53
m b=4x+9=4(7)+9=28+9=37
angle a measures 53 degrees
angle b measures 37 degrees
The answer would be D. Infinite
None of these because they all are 0
Answer:
The value of given log function is 1 .
Step-by-step explanation:
Given as :
Logb A = 3
Logb C = 2
Logb D = 5
<u>Now from log property </u>
if , Logb x = c , then x = 
So,
Logb A = 3 , then A = 
Logb C = 2 , then C = 
Logb D = 5 , then D = 
Now, According to question

So, 
Or, 
or, 
Now, since base same So,

∴ 
<u>Now log property </u>
= 1
Hence The value of given log function is 1 . answer
