Answer:
cos Θ = 
Step-by-step explanation:
Given the angle passes through (4, 5 ) then the right triangle with sides 4 and 5 has hypotenuse h given by
h² = 4² + 5² = 16 + 25 = 41 ( take the square root of both sides )
h = 
In relation to Θ, 4 is adjacent and 5 is opposite, thus
cos Θ =  =

Answer:
57cm²
Step-by-step explanation:
area for trapezoid= 
b¹+b²=x
x÷2=v
v×h=z
h=height 
b=base
14+5=19
19÷2=9.5
9.5×6=57
