Answer: 37
Step-by-step explanation:
Sin = - 4/8
Quadrant IV = only cosine is positive
a = height (4)
b = base ( 8^2-4^2=b^2
b = 6.93 @

c = hypothenuse(8)
cos =

/8
tan = - 4/

sec = 1/cos
1/cos = 1/ (

/8)
sec = 8/

csc = 1/sin
1/sin = 1/(-4/8)
csc = - 2
cot = 1/tan
1/tan = 1/(-4/

)
cot = -

/4
Answer:A
Step-by-step explanation:
Answer:
7 degrees
Step-by-step explanation:
It has a right angle and it's a triangle so the angle is a complementary angle so the total for the angle is 90 degrees.
So then you add 39 + 44 and get 83
So, 90 - 83 +7
So your total is 7 degrees
Answer:
Thus, option (c) is correct.
β = 61.5
Step-by-step explanation:
Given ,
, we have to solve for x, and then find the value of β ( β > α )
Consider
,
First solve for x ,


Thus, 
Also,
, we get,
Thus, 
since, LHS = RHS thus, angle must be equal,





Thus,
,
Other angle can be found using angle sum property, as sum of angle of a triangle is 180°
Let third angle be y, then ,
90 + 61.5 + y = 180°
y = 180° - 151.5°
y = 28.5°
Since ( β > α ) ⇒ β= 61.5 and α = 28.5
Thus, option (c) is correct.
⇒ β = 61.5
