Answer:
-57/25 or -2 7/25 or - 2.28
Step-by-step explanation:
Answer:
None, they are not similar.
You can tell by trying to match ratios with others.
55:42:36
(I put them least to greatest order because triangles cannot really like change only one sides' value, so it makes it visually easier to comprehend.
8:7:5
I can't see any possible way to relate these two ratios together.
The 5 cannot go into 36 anyhow, and like the 8 and 55. The 7 can be multiplied by 6 to get 42, but 5 and 8 cannot reach their own numbers.
Step-by-step explanation:
I shall accept every question from your profile >:)
5/7=110/154 so the answer is 154
36 over 121 cannot be simplified, it is already in its simplest form.
D1=25°
B3=25°
B1=30°
Step-by-step explanation:
1. O1+O2=360°(revolution)
310°+O2=360°
O2=360°-310°
=50°
O2=2D1(centre theorem)
50°=2D1
D1=25°
2. D1=B3=25°(tan chord theorem)
3. B2+B3=A=60°(tan chord theorem)
B1+B2+B3=90°(Radius perpendicular Tangent)
B1+60°=90°
B1=90°-60°
=30°
