This triangle is an isosceles triangle because there are two angles which measure 54° and one angle which measures 72°
Answer:
-3/22
Step-by-step explanation:
Mulitiply straight across. Num * num/ denom * denom.
Now you have -6/44. Divide both by 2 to simplify into simipliest form.
Step-by-step explanation:
csc x / (cot x + tan x)
Write in terms of sine and cosine.
(1 / sin x) / [(cos x / sin x) + (sin x / cos x)]
Multiply top and bottom by sin x.
1 / [cos x + (sin²x / cos x)]
Multiply top and bottom by cos x.
cos x / (cos²x + sin²x)
Use Pythagorean identity.
cos x / 1
cos x
If this is for a better deal if you made the prices the same so instead of 5 for six itd be 50 for $60 and 8 for $10 would be 48 for $60 obviously 5 for 6 is the best choice. thats just how i was taught i hoped this helps
