Consider the proof. Given: In △ABC, BD ⊥ AC Prove: the formula for the law of cosines, a2 = b2 + c2 – 2bccos(A) Statement Reason

loris [4]

Solution: The missing reason in Step 8 is substitution of $x=c\cos (A)$ .

Explanation:

The given steps are used to prove the formula for law of cosines.

From step 5 it is noticed that our equation is

$a^2=b^2-2bx+c^2$ ..... (1)

From step 7 it is noticed that the value of $x$ is $c\cos (A)$ .

So by substituting $c\cos (A)$ for $x$ in equation (1) we get the equation of step 8, i.e.,

$a^2=b^2-2bc\cos (A)+c^2$

Hence, the missing reason in Step 8 is substitution of $x=c\cos (A)$ .

Solve each proportion.<br> 2/4=4/p-3<br>pls help

eduard

Answer:

$p=\frac{8}{7}$

Step-by-step explanation:

$\frac{2}{4} = \frac{4}{p} - 3$

$\frac{1}{2} = \frac{4}{p} - 3$ (simplify)

$\frac{1}{2}+3 = \frac{4}{p} - 3+3$

$\frac{1}{2}+3 = \frac{4}{p}$ (Add 3 to both sides)

$\frac{7}{2}= \frac{4}{p}$ (simplify)

$\frac{7}{2}p= \frac{4}{p}*p$

$\frac{7p}{2}=4$ (Multiply both sides by p)

$\frac{7p}{2}*2=4*2$

$7p=8$ (Multiply both sides by 2)

$\frac{7p}{7}=\frac{8}{7}$

$p=\frac{8}{7}$ (Divide both sides by 7)
