The answer to this is 65.
Remember that the angles opposite of each other equal to 180. So a+c=180 and b+d=180.
First, we solve for x. Since we know that b and d equal to 180, we subtract 148 from 180.
180-148=32. x=32.
Then we plug that in the expression for angle a.
2x+1 becomes 2(32)+1
2*32=64
64+1=65.
a=65
Answer:
The expression will be 
Step-by-step explanation:
We have given expression 
We know the property of exponent that when two function are divided then the power of exponent is subtracted and when there is multiplication of two function then exponent is added
So 
So the expression will be
The answer is A because both numbers can be divided by 6 to get 5 : 9
The first thing we are going to do for this case is to define the following variable:
x = number of trees.
We then have that the equation that represents the problem is given by:
y = 50 (x-1) + 20
Rewriting:
y = 50x - 50 + 20
y = 50x - 30
Substituting for y = 390 we have:
390 = 50x - 30
We clear x:
x = (390 + 30) / (50)
x = 8.4
nearest whole integer
x = 8
