If the sine if 4/5, then the side opposite is 4 and the hypotenuse is 5. This means it's the 3, 4, 5 right triangle (or similar, such as 6, 8, 10).
cos = 3/5
tan = 4/3
cot = 3/4
sec = 5/3
csc = 5/4
85=d/3.75
d = 85 x 3.75
d = 318.75
Answer:
wy=root 5
maybe 30 and 60 degree
Step-by-step explanation:
Isolate the d
divide 7 from both sides
c/7 = 7d/7
c/7 = d
d = c/7 is your answer
hope this helps
Answer:
The first blank is 81
+9=x-1
The second blank is 9x+3=x^2-1
Step-by-step explanation:
For the first part, you must set up the equation (9x+3)^2 then you must multiply the exponent to the inside exponents 
+
next, simplify.
81+9=x-1
For part two, set up equation. 
Then simplify 9x+3=
