Answer:
We can use the sine law to find h. First, we determine the angle between the line of sight and h:
180 - 90 - 39 = 51 degrees
The sine law states that the ratio of one triangle's angle to the opposite side's length is the same as another angle to its opposite side's length, so we can solve for h as follows:
h/sin(39) = 500/sin(51)
h = 500*sin(39)/sin(51)
When we round to the nearest whole number, we get h = 405 ft.
The x intercept in this mathmatical equation is 1
Answer:
they are not equal
Step-by-step explanation:
-8v-12=-8v-12
4v+12=4v+12
but you can solve it as an equation
-8v-12=4v+12
make v the subject
-8v-4v=12+12
-12v=24
divide both sides by-12
your answer is-2
if you put them into desmos (online website) it will put them all into a graph and do it for you :)
Since a square is equal on all 4 sides, that means each side would be 5, because 20/4=5
so using the Pythagorean thrm (which we can use since a square has all 90 degree angles)
a=5 b=5 c=?
5^2+5^2=c^2
25+25=c^2
50=c^2 *square root both sides*
c= 7.07
So the answer would be 7.1
