Answer:
x=21
y=45
z=101
Step-by-step explanation:
Angles crossing each other are congruent
86=4x+2
84=4x
x=21
Quadrilateral has 360 degrees
86 + 86 + 2y+4 + z-7 = 360
172 + 2y+4 + z-7 = 360
2y+4=94
2y=90
y=45
z-7=94
z=101

Answer:
20
Step-by-step explanation:
a^2 + b^2 = c^2
12^2 + 16^2 = c^2
144 + 256 = c^2
400 = c^2
20 = c
The length of BC = 20
The answer is 1.91 m
It is given:
S = 2 π r l
S = 36 m²
r = 3 m
l = ?
π = 3.14
So, let's just solve this:
36 = 2 · 3.14 · 3 · l
36 = 18.84 · l
⇒ l = 36 ÷ 18.84
⇒ l ≈ 1.91 m
