Applying the Pythagorean Theorem
Find the lengths of the two sidewalks
Step 1
square section
D=√{15²+15²}
D=√450 m
D=21.21 m
Step 2
rectangular section
D=√{15²+8²}
D=√289 m
D=17 m
Step 3
the sum of the lengths of the diagonals of the two sections is
17m + 21.21 m = 38.21 m
the answer is
38.2 m
Step-by-step explanation:
chorus is harder while sociology is not hard
So I think the hatch mark on the two sides means the lines are congruent, and it appears that the angles at the top of the triangle are congruent. If so, that would mean that the center line is a bisector of the bottom part of the triangle. This would mean that 16 + x = 8, so x = -8.
Answer:
9 m²
Step-by-step explanation:
s = half the perimeter = (a+b+c)/2
the perimeter in our case is
a+b+c = 16
so, s = 16/2 = 8
and the sides are
7 m
6 m
16 - 7 - 6 = 3 m
therefore, we get
area = sqrt(8(8-7)(8-6)(8-3)) = sqrt(8×1×2×5) = sqrt(80) =
= 8.94427191... ≈ 9 m²
Answer:
Step-by-step explanation:
Slope m = 9
Intercept c = 0
And y = mx + c
Substituting the values
y = 9x
