The smallest angle is a which is 35 and from 7 to 35 it X5 so times 18 and 11 by 5 as well which comes to the ratio 35:90:55 , you can tell this is right because angles in a triangle add up to 180 , 35+90+55 =180

2. Solve for y. A 10.5 B 9 C 13.5 D 12

Vera_Pavlovna [14]

It’s A
Because if you subtract 12 from 96 you’ll get 8y=84 then divide both sides by 8 you get 21/2 simplify and get 10.5 or 10 1/2

Need an explanation on number 44 to why E is correct

aliina [53]

Before we can make sure that E is correct, we need to make the denominator is equal with questions and the choices or convert into decimal.

2/3 = 0.66

1/3=0.33

1/5=0.2

2/6=1/3 = 0.33

1/2 = 0.5

7/10 = 0.7

7/9 = 0.77

The question is :

2/3 < x < 7/9

0.66 < x < 0.77

We need to divide into 2 parts :

0.66 < x

x < 0.77

So we need to find the answer that x is greater that 0.66 and we got 7/10. And 7/10 is less than 7/9.

Hope this helps. Please ask if you don't understand.
