The answer is D:10 cm, I just took it and got this.
Answer:
Proving an identity is very different in concept from solving an equation.
Step-by-step explanation:
because it Though you'll use many of the same techniques, they are not the same, and the differences are what can cause you problems.
Answer:
add both of those up and see what you get
Step-by-step explanation:
Answer:
30
Step-by-step explanation:
5(z+4)+5(2-z) (expand parentheses by distribution)
= z(5) + 4(5) + 2(5) -z(5)
= 5z + 20 + 10 -5z
= 30

Answer: x = 18 (choice B)</h3>
===================================
Work Shown:
Through the inscribed angle theorem, we can say that 2 times the inscribed angle gets us the arc that the inscribed angle cuts off.
2*(inscribed angle) = arc measure
2*(2x+2) = 76
4x+4 = 76
4x+4-4 = 76-4 ... subtract 4 from both sides
4x = 72
4x/4 = 72/4 ... divide both sides by 4
x = 18
