Answer:

Alloy = 12.6 lbs.

Step-by-step explanation:

( 2/7 ) = ( Nickel /4.9)

Nickel = 1.4 lbs.

Ratio of Copper to Zinc:

( 9/7 ) = ( Copper /4.9)

Copper = 6.3 lbs.

Alloy = Zinc + Nickel + Copper

Alloy = 4.9 lbs. + 1.4 lbs. + 6.3 lbs.

Alloy = 12.6 lbs.

<u><em>The correct question is</em></u>

If b = 9 and c = 13, what is the measure of ∠A? (round to the nearest tenth of a degree)

The picture in the attached figure

we know that

In the right triangle ABC

$cos(A)=\frac{b}{c}$ ---> by CAH (adjacent side divided by the hypotenuse)

substitute the given values

$cos(A)=\frac{9}{13}$

using a calculator

$A=cos^{-1}(\frac{9}{13})=46.2^o$
