1150, i’m pretty sure that’s it!
Solution: The missing reason in Step 8 is substitution of
.
Explanation:
The given steps are used to prove the formula for law of cosines.
From step 5 it is noticed that our equation is
..... (1)
From step 7 it is noticed that the value of
is
.
So by substituting
for
in equation (1) we get the equation of step 8, i.e.,

Hence, the missing reason in Step 8 is substitution of
.
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

Answer:
x = 76
Step-by-step explanation:
The inscribed angle x is half the measure of its intercepted arc.
x =
× (102 + 50) = 0.5 × 152 = 76
