Using a right triangle formed by boat with base and top of lighthouse.Note: 15 minutes = 0.25 degreesLet d be distance the boat is from shore.tan(90−13.25)=d/175
d=175∗tan(76.75)=743.2
The identity property of addition states that the sum of any number and 0 is the original number.
so...x + 0 = x would be the identity property of addition (also called the additive identity)
Answer:
75
Step-by-step explanation:
Four scores.... add them together and divide by four
(90 + 80 + 70 + 60) / 4 = 75
To solve for x just isolate x by moving the other variables so....:
First add c to both sides
g+c= y+x
Subtract y from both sides
g+c-y= x
That should be your final answer (we cannot come up with an actual digit for x because there are no numbers in this equation we simply can make an equation for x)
