(A) 1.8
The difference is 18, 13 is bc the tenth term so divide 18 by 10 to get 1.8
Answer:
The length of BC is 17 units
Step-by-step explanation:
we know that
An isosceles triangle has two equal sides and two equal angles
In this problem we have an isosceles triangle
Because
m∠ACB=m∠ABC ----> given problem
so
AC=AB
substitute the given values

solve for x


therefore
The length of BC is 17 units
Answer:
220 yards
Step-by-step explanation:
Answer:
(-2, 8) and (5, -1)
slope: (y² - y¹) / (x² - x¹)
(-1 - 8) / (5 + 2) = -9/7
y = -9/7x + b
8 = -9/7(-2) + b
8 = 18/7 + b
8 = (2.57) + b
b = 5.43
y = -9/7x + 5.43
parallel = same slope
y = -9/7x
perpendicular = reciprocated slope
y = 7/9x
