Answer:
30 or -30
Step-by-step explanation:
y^2 = 900
Take the square root of each side
sqrt(y^2) = sqrt(900)
y = ±30
Y = x³-1
y = 2³ -1
y = 8 -1
y = 7
Third option. They cancel eachother out therefore it'd be 0
A) The hypotenuse is the longest side of the triangle .In the figure EG is the hypotenuse.The given angle is <G=40 degrees.The side adjacent is FG= 10 units.
The question is asking us to find the trigonometry ratio which will help us find EG.We can use cos as cos is ratio of adjacent and hypotenuse.
B) Cos 40 =0.766.
Substituting tan40 value we have:
EG=13.05.
C)Sum of angles in triangle is 180.
<E+<F+<G=180
<E+90+40=180
<E+130=180
<E=50 degrees.
D)
EF=8.39
E) Area of triangle EFG=
A rea of the triangle =
Area= 54.75 square units.
