Personally I used desmos in algebra it gives you the visual representation x=
Answer:
27 Degree
Step-by-step explanation:
First Draw the graph (If you want)
Tan is what we have to use because TAN = Opposite / Adjacent
TanA=2/4
TanA=1/2
TanA=0.5
Tan^-1 x (0.5)
<A= 26.565...
ROUND TO THE NEAREST DEGREE = 27 Degrees
small frames ($8): s
large frames ($15): L
Cost: 8s + 15L = 239 ⇒ 1(8s + 15L = 239) ⇒ 8s + 15L = 239
Quantity: s + L = 22 ⇒ -8( s + L = 22) ⇒ <u> -8s -8 L = -176 </u>
7L = 63
L = 9
Quantity: s + L = 22 ⇒ s + (9) = 22 ⇒ s = 13
Answer: 13 small frames, 9 Large frames
Answer:
i think 4 th option
if u want to verify just substitute (4,-2)
