Answer:
if sin (x-3) degrees = cos (2x+6) degrees, find the value of x.
----------
Note: sin and cos are complementary functions....
sin(x) = cos (90-x)
-------------------
Your Problem:
sin(x-3) = cos(90-(x-3))
Equation:
90-[x-3] = 2x+6
90-x+3 = 2x+6
3x = 93-6
x = 31-2
x = 29
Step-by-step explanation:
Answer:
S: (2,8)
T: (2,9)
U:(-6,9)
V:(-6,8)
I'm 95% sure since ive done these before.
Slope = 0
⇒ It is a horizontal like that cuts through the y-axis
At point (5, -8), y = -8
The equation of the line is y = -8
-----------------------------------------------
Answer: y = -8

Answer:
The area of the trapezium is 
Step-by-step explanation:
Area of a trapezium:

This formula is valid if b1 and b2 are parallel and h is perpendicular to both.
Since the trapezium given in the problem satisfies those conditions, we use the formula with:
b1=15 cm
b2=7 cm
h=6.8 cm


The area of the trapezium is 
15*$7.70= $115.50
18*$7.70=$138.60
$115.50+$138.60= $254.10
His pay for the two-week is $254.10
