Answer:
-22d -102
Step-by-step explanation:
8(−5d−9)−3(−6d+10)
Distribute
-40d -72 +18d -30
Combine like terms
-40d +18d -72 - 30
-22d -102
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.
Answer: 17.5 square yards
================================================
Work Shown:
base = 5 yards
height = 7 yards
The base and height are always perpendicular to one another
area of triangle = 0.5*(base)*(height)
area of triangle = 0.5*(5)*(7)
area of triangle = 17.5 square yards
The other values aren't used. They're likely thrown in as a distraction.
The first one is 21.93 rounded up to 22.
