Answer:

A) -8

Step-by-step explanation:

First lets plug in -8

-2= 4 + x /2

-2= 4 + (-8) /2

-2= -4/2

-2= -2

That is a true statement so now we know X= -8

Hope this helped! Have a good/night!

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).

KIM [24]
Alright so if you have a negative number let's say -5 if you put the absolute value symbols around it like so |-5| then it becomes positive. Whatever is in the lines becomes positive, that's why I call it the positive box. It describes the distance of a number on the number line from 0 without considering which direction from zero the number lies. The number is never negative

Find the measure of the missing angle.
natulia [17]

Answer:

x = 76

Step-by-step explanation:

The inscribed angle x is half the measure of its intercepted arc.

x = \frac{1}{2} × (102 + 50) = 0.5 × 152 = 76
