Answer:
perimeter is adding so add all the sides
Step-by-step explanation:
Answer:
Sides in descending order: YZ > ZX > XY
Step-by-step explanation:
Sum of all angles of triangle = 180
104 +52 + ∠Z = 180
156 + ∠Z = 180
∠Z = 180 - 156
Z = 24
The sides opposite to the biggest is the longest side.
Angles in descending order: ∠X > ∠Y > ∠Z

Sides in descending order: YZ > ZX > XY</h3>
Answer:(2.85,-1.65)
Step-by-step explanation:
Add both "x" coordinates, divide by 2.
Add both "y" coordinates, divide by 2.
Answer:
(a) 1.4 hours or 1 hour 24 minutes.
(b) 15 miles.
(c) (5/6)t miles.
(d) 70 - (5/6 t miles.
Step-by-step explanation:
(a) speed = distance / time
50 = 70 / t
t = 70/50
t = 7/5
t = 1.4 hours.
(b) 18 minutes = 18/60 = 0.3 hours.
50 = distance / 0.3
distance = 50 * 0.3
= 15 miles.
(c). 50 = d / (t/60)
50 = 60d / t
60d = 50t
d = (5/6) t miles.
(d) Number of miles remaining after t minutes = 70 - (5/6) t miles.
There is a 45,45,90 triangle and a 30,60,90 triangle within triangle ABC.
So you can just use the relationships between sides in these special triangles to find the desired lengths.
AB=3√2
z=3
b=3 (It is isosceles so we know that b=z)
With b=3, we know that...
x=3·2=6
y=3√3
answers: z=3,b=3,x=6,y=3√3
