Answer:
x = 38°
Step-by-step explanation:
x and the 142° angle are supplementary angles, meaning they add up to 180°
x + 142° = 180°
Subtract 142 from both sides.
x = 38°
It would be 19. Because...
Expression: $0.55n = $10.45
Work: 10.45 / 0.55 = 19 ounces
Proof: 19 x 0.55 = $10.45

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
Answer:
Step-by-step explanation:
A = mR - R
R(m - 1) = A
R = A / (m - 1)
