Answer:
93 degrees
Step-by-step explanation:
First, you would need to observe the image and see where to start off. You can see that there is a triangle below the "?" and you would be able to get the answer if you can find the measures of the small triangle(because of vertical angles) So,
180-127= 53.
180-146=34.
Since the angles of a triangle adds up to 180 degrees, 53+34+x=180.
x=93
Now, just flip the angle around and "?" = 93 degrees.
Answer: 3.875 or 3ft 7/8in
=15.5 - 3.875(3)
=15.5 - 11.625
= 3.875 or 3ft 7/8in
Answer:
x=9
Step-by-step explanation:
5( x + 7) - 3 ( x - 4) = 7x + 2
Distribute
5x+35 - 3x +12 = 7x +2
2x +47 = 7x+2
Subtract 2x from each side
2x+47-2x =7x -2x+2
47 = 5x+2
Subtract 2 from each side
47-2= 5x+2-2
45= 5x
Divide by 5
45/5 =5x/5
9 =x
Answer:
D) 12%
Step-by-step explanation:
The merchant marks his wares 40% more than the real price.
The merchant also allows 20% discount.
Let the real price = 100
After a 40% mark up, the price becomes
(40 /100) * 100
= 40
So we have 100 +40= 140
Discount of 20% = (20/100)* 140
= 28
The price is 140 - 28 = 112
Profit = 112 -100
= 12%
Your answer will be B
base x length x height
