So attached is a picture of the triangle you are talking about and listed under are the choices:
A.) Cos Z=b/c
B.) Sin X=c/b
C.) Tan X=b/a
<span>D.) Tan Z=a/b
</span>
The answer would then be B. SinX = c/b.
Just remember SOH CAH TOA:
Sinθ= Opposite Cosθ = Adjacent Tanθ= Opposite
Hypotenuse Hypotenuse Adjacent
Using the triangle in the scenario, you just need to identify which side is which.
Given m∠Z
Adjacent = b
Opposite = a
Hypotenuse = c
SinZ= a CosZ = b TanZ= a
c c b
Given m∠X:
Adjacent = b
Opposite = a
Hypotenuse = c
SinX= <u> b </u> CosX =<span><u> a </u></span> TanX=<span><u> b </u></span>
c c a
So the answer is B.
Attached is a picture of how I assigned the sides depending on the angle used.
A.) Cos Z=b/c
B.) Sin X=c/b
C.) Tan X=b/a
<span>D.) Tan Z=a/b

Hypotenuse = c
SinX= <u> b </u> CosX =<span><u> a </u></span> TanX=<span><u> b </u></span>
c c a
So the answer is B.

Answer:
The number of bricks a truck can carry in full load is 308 .
Step-by-step explanation:
Given as :
The weight of each brick = 4 pounds and 14 ounce
The total load a truck can carry = tons
Let The number of bricks truck can carry = n bricks
<u>Now, According to question</u>
∵ 1 ounce = 0.0625 pounds
∴ 14 ounce = 0.0625 × 14 = 0.875 pounds
So, Total weight of each brick = 4 pounds + 0.875 pounds = 4.875 pounds
<u>Again</u>
∵ 1 pound = 0.0005 tons
∴ 4.875 pounds = 0.0005 × 4.875 = 0.0024375 tons
<u>Now, Again</u>
The total load a truck can carry = tons = 0.75 tons
And The weight of each brick = 0.0024375 tons
So, The number of bricks =
I.e n =
∴ n = 307.69 ≈ 308
So, The number of bricks can truck carry = n = 308
Hence, The number of bricks a truck can carry in full load is 308 . Answer
