Answer:
cos(A)=sin(26.57°)=0.447
Step-by-step explanation:
we know that
In the right triangle ABC
The angle A and the angle C are complementary angles
so
∠A+∠C=90°
therefore
cos(A)=sin(C) -------> by complementary angles
we have
C=26.57°
sin(26.57°)= 0.447
Hence
cos(A)=sin(26.57°)=0.447

Answer:
c) The total price for the service when Terrance's price was equivalent to Sylvester's price is $600.
Step-by-step explanation:
Here, t = 320.00 + 0.40 b
and t = The total prices charged by Terrance for packing and moving b boxes.
s = 250.00 +0.50 b
and s = The total prices charged by Sylvester for packing and moving b boxes.
Now, to find the number of boxes, when both the prices are equal.
⇒320.00 + 0.40 b = 250.00 +0.50 b
or, 320 - 250 = 0.50 b - 0.40 b
or, 0.10 b = 70
or, b= 70/0.10 = 700
Hence, for packing and moving b = 700 boxes, both companies charge the same amount.
Now, the price charged = 320 + 0.4 (b)
= 320 + 0.4(70) = 320 + 280
= 600
or, the total price for the service when Terrance's price was equivalent to Sylvester's price is $600.
