I got B but I'll show you how I got that answer.
Let's look at AB and BC. AB = 3 and BC = 4.
3/4 = 0.75
On the triangle, AB = 90. And BC = 10x - 20. We need to solve for x and prove that AB/BC = 0.75.
Let's start with Choice A.
10(11) - 20 = 90.
AB = 90
BC = 90.
90/90 = 1. It doesn't equal 0.75. Meaning this answer is wrong.
Now let's look at Choice B.
10(14) - 20 = 120.
AB = 90
BC = 120
90/120 = 0.75
So, 3:4 = 90:120 making Choice B the correct Answer. Let me know if this is correct
2
Because -
2 x 12=12
2 x 13 = 36
2 x 42 = 84
Answer:
200
Step-by-step explanation:
The nearest ten for 155 would be 200
90 is 1 half of 180. This is because 90 times 2 is 180. If you were to check your work and divide 180 in half you would get 90.
Hope this helps :)
