Answer:
See explanation
Step-by-step explanation:
We have to prove the identity
We will take right hand side of the identity
[ Tan θ will be positive since θ lies in 1st quadrant ]
Answer:
Step-by-step explanation:
You mean to find side (hypotenuse) x and angles y and z in the right triangle.
We will find hypotenuse with Pythagorin theorem
x∧2 = 10∧2 + 8∧2 = 100 + 64 = 164 => x = √164 = 12.80
x = 12.80
According to the definition of tangens we have
tan y = 8/10 = 0.8 => y = arc tan 0.8 = 38.66° => y = 38° 39' 36''
tan z = 10/8 = 1.25 => z = arc tan 1.25 = 51.34° => z = 51° 20' 24''
God with you!!!
In this question, Vanessa is doing 3 math quizzes and then doing 1 more which makes a total 4 test. She wants to get 49 average scores, so the total score she needs to have should be: 4*49= 196 scores.
Then the next score that Vanessa should get in her 4th score:
Total score= score1 + score2 + score3 + score2
196 = 45+ 32 +37 +score4
196= 114+ score 4
score 4= 196 -114= 82
