Sin 3A = cos (A – 70ᵒ), where A is an acute angle then<br> A = ________________ ᵒ.

romanna [79]

Answer:

A = 40°

Step-by-step explanation:

$\sin 3A = \cos (A – 70ᵒ) \\ \\ \cos(90 \degree - 3A) = \cos (A – 70ᵒ) \\ \{\because \: \cos(90 \degree - \theta) = \sin \theta \} \\ \\ (90 \degree - 3A) = (A – 70ᵒ) \\ \\ 90 \degree + 70ᵒ = 3A + A \\ \\ 160 \degree = 4A \\ \\ A = \frac{160 \degree}{4} \\ \\ \huge \red{ \boxed{A = 40 \degree}}$

A restaurant manager wants to purchase 200200 sets of dishes. one design costs $1010 per set, while another costs $5555 per s

Sophie [7]

Unless it was a restaurant for the king ..... i am going to assume your
200200 is 200
$1010 is $10
$5555 is $55
$78507850 is $7850

Let x be the number of $10 design set
$10 design set = x
$55 design set = 200 - x

10x + 55(200 - x) = 7850
10x + 11000 - 55x = 7850
55x - 10x = 11000 - 7850
45x = 3150
x = 70
200 - 70 = 130

70 of the $10 design and 130 of the $55 design
