Malik considers the enlargement of the trapezoid. The side with the length 10 cm becomes the side with the length 25 cm, the side with the length 18 cm becomes the side with x cm.
Write a proportion of corresponding sides:
Cross multiply:
so correct option is C,
(18)(25) =10x
Step-by-step explanation:
Answer:
C=2
Step-by-step explanation:
Because I got it correct in AP3X
1) x=-3. The missing angle is 71 degrees
2) x=45. The missing angles are 90 and 45 degrees.
3) x=40. The missing angles are 40 and 100 degrees
Answer:
2a + 3b = 5
b = a - 5
Step-by-step explanation:
2a + 3b = 5
b = a - 5
You can write this another way:
2a + 3(a-5) = 5 ( I added the second formula in the first one )
Now you gotta factor out:
2a + 3a - 15 = 5
Here im gonna do plus 15
2a + 3a = 20 ==> 5a = 20
Now if you divide by 5, you get: a = 4
Now you can fill in the second formula again
b = a - 5 (ill fill this in now)
b = 4 - 5 = -1
So, this makes:
a = 4 , b = -1
