A triangle, it might be an obtuse
Answer:
2. 6/9
3.2/4
4. 8/10
Step-by-step explanation:
basically the idea is to find something in the same fact family so like the example on 1, follow that and try to answer the next problams on your own its really easy
( sorry if im wrong or not i tried to help)
Answer:Tag 30*(2\/3)=x
Step-by-step explanation:
Tag 30*= x/2\/3;
Tag 30*(2\/3)=x
check the picture below on the top side.
we know that x = 4 = b, therefore, using the 30-60-90 rule, h = 4√3, and DC = 4+8+4 = 16.

now, check the picture below on the bottom side.
since we know x = 9, then b = 9, therefore DC = 9+6+9 = 24, and h = b = 9.
