To find x, substract 72 and 78 from 180 since all triangles are 180°
180 - 72 - 80 = 30
So x = 30
To find y, x and y equal 180 so subtract 30 from 180
180 - 30 = 150
y = 150
x = 30, y = 150
Answer: 7.07 miles
Step-by-step explanation:
Hi, to answer this, first, we have to find the length of the square dog pen.
Perimeter of a square = 4 x sides
Replacing with the value given:
20 = 4 s
Solving for s:
20/4=s
Side = 5 meters
Since the situation forms a right triangle (see attachment) we have to apply the Pythagorean Theorem:
c^2 = a^2 + b^2
Where c is the hypotenuse of the triangle (in this case length of the diagonal) and a and b are the other sides.
Replacing with the values given:
c^2 = 5^2 + 5^2
c^2 = 25+25
c^2 = 50
c = √50
c = 7.07 miles

The 4th term is -7 . because you put 4 where n is t(n)=(-3•4)+5
