Answer:
Area=77
Step-by-step explanation:
P=36
P=2l+2w
l=w+4
P=2(w+4)+2w
P=2w+8+2w
P=4w+8
36=4w+8
28=4w
w=7
l=7+4
l=11
A=lw
A=77
4•4=16
12•5=60. That’s the answer

Answer:
(b) tan B = 8/6
Step-by-step explanation:
The mnemonic SOH CAH TOA is intended to remind you of the relevant relationships:
Cos = Adjacent/Hypotenuse
Tan = Opposite/Adjacent
Then angle B is involved in tangent and cosine relationships this way:
tan B = 8/6 . . . . . . matches 2nd choice
cos B = 6/10 . . . . . matches no choices
_____
<em>Additional comment</em>
Both of the offered cosine choices give a cosine value that is greater than 1. The cosine of a real angle is never greater than 1, so those can be rejected immediately.
