Answer:
51
Step-by-step explanation:
sum of exterior angles = 360
64 + 60 + 69 + 42 + x + x +23 = 360
2x + 258 = 360
2x = 360 - 258
2x = 102
x = 51
The "distance formula" an extension of the Pythagorean Theorem is:
d^2=(x2-x1)^2+(y2-y1)^2 in this case:
d^2=(-8-7)^2+(-9--1)^2
d^2=(-15)^2+(-8)^2
d^2=15^2+8^2
d=√(15^2+8^2)
So the answer is 15^2+8^2
2 i believe because if .25 is equal to 1/8 then that mean the 4/8 would be equal to 1 and in turn 8/8 would equal 2.
X-9^2
a number = x
decreased= subtracting
square of 9= 9^2
Its c because 11/10 gives you a whole number
