Answer:
Step-by-step explanation:
Tan 145 = - 0.7002
Tan 85 = 11.43
Tan 145 + tan 85 = 10.7298
1 - tan(145)* tan(85) = 9.003
(Tan(145) + Tan(85)) / (9.003)
= 10.73 / 9.003
= 1.1918
I misread the question. If you mean
(Tan145+tan85) /1-tan145*tan85 (brackets are really important here)
then the answer is
Tan(145 + 85)
= Tan(230)
= 1.1918
Answer:

Step-by-step explanation:
I am assuming this problem reads 
- So let's start on the outside and work our way towards the middle
- Starting with the
, this can be simplified to
Now we have 
- Now simplifying what is inside the parenthesis we get
- Combining what we have the simplified for of the problem becomes:

Answer:
62°
Step-by-step explanation:
180-118=62
62+62=124
180-124=56
118-56=62
Answer:
0.920
Step-by-step explanation:
To calculate this, we proceed to the t-table
Using degree of freedom 5 and significance level of 0.2, the t-value is 0.920
