Answer:
39
Step-by-step explanation:
y=arctan(0.8)=38.65=39
Answer:
5. a,c,b
6. a,b,c
7. v,z,y,w,x
Step-by-step explanation:
5. Given are the measure of sides as 28,17 and 15. The corresponding angles are 'a', 'c' and 'b'.
Using the conjecture: The angle opposite to the greatest side is largest.
Thus for the sides 28,17 and 15. The corresponding angles 'a', 'c' and 'b' are in order from greatest to least.
6. Given are the angles 30, 72 and 75( angles of an isosceles triangle).
Using the conjecture: The angle opposite to the greatest side is largest.
We observe
'a' is corresponding to angle 75°
'b' is corresponding to angle 72° and
'c' is corresponding to angle 36°
Thus a,b,c are the order from greatest to least.
7. Given
'v' is corresponding to angle 122° [180-(30+28)]
'w' is corresponding to angle 42°
'x' is corresponding to angle 34°
'y' is included in three dimensional angle
'z' is included in three dimensional angle
Such that
Thus the order from greatest to least is v,z,y,w,x

What is the value of x when f (x) = 4?
Answer:f(4)= 12
Step-by-step explanation:
Treat f(x) as y, y=2x + 4, y=12
Answer:
x = 0
Step-by-step explanation:
Given f(x) = x² + 4 and f(x) = 4, then equating
x² + 4 = 4 ( subtract 4 from both sides )
x² = 0 , thus
x = 0
Answer:
(x)= -9
Step-by-step explanation:
because 4×9=36 and there is a negative sing in front of the nine do the answer would be 4×-9=-36. A negative times a positive I'd a negative.
Answer:
P≈76.37
Step-by-step explanation:
Using the formulas
P=4a
d= √2a
Solving for P
P=2√2d=2·√2·27≈76.36753
