Answer:
22in.^2
Step-by-step explanation:
Area of a triangle formula is A= b*h* 1/2
(b= base h= height)
the base is 8
the height is 5 1/2
8*5 1/2
----------
2
5 1/2 = 5.5
8* 5.5 = 44
44/2 = 22
Answer:
x=34
Step-by-step explanation:
36-2x=-x+2
add x to both sides and subtract 36 from both sides
-x=-34
x=34
First you want to get it into standard form. which would mean you get the x of the side of the y and divide everything by the y's coefficient in this case 3.
3y-x=a
3y=x+a
y=1/3x+a
Now your going to want to turn this into a perpendicular li e which means you flip the coefficient and make it negitive
y=-3x+a
then we fill in the points.
-1=-3(2)+a
Solve
-1=-6+a
-1+6=a
5=a
Now put it in standard form.
y=-3x+5
Answer:
sin θ = 
Step-by-step explanation:
Given that,
cos θ = 
From the trigonometric functions,
cos θ = 
⇒ adjacent = 
, and the hypotenuse = 3
Let the opposite side be represented by x, applying the Pythagoras theorem we have;
= 
+ 
= 
+ 
9 = 3 +
= 9 - 3
= 6
x = 
Thus, opposite side =
So that,
sin θ = 
=
Therefore,
sin θ =
