Then,
$92 per cot
96 cots
(96x92=$8,832)
$8,832
Answer: That is a Acute angel and a Obtuse angel
Step-by-step explanation: I know that thats an Acute Angel because its shaped like one and looks like one and Acute angels are only 79% of Area. Than the 13 cm will be a 60% obtuse Angel.
The acceleration of the fire truck is 1.666 m/s².
<u>Step-by-step explanation:</u>
Acceleration is the measure of change in velocity with respect to time. So as the initial velocity of the fire truck is given as 0 km/hr and the final velocity is given as 66 km/hr. So at first the truck is at rest and on switching on the engine, the truck gets to the velocity of 66 km/hr in 11 seconds.

But first the units of velocity should be changed from km/hr to m/s
1 hour = 3600 seconds
1 km = 1000 m
So, 
Converted Velocity = 18.33 m/s
Then, the acceleration will be

Acceleration = 1.666 m/s²
So, the acceleration of the fire truck is 1.666 m/s².
Distributive property states a(b+c) = ab + ac
9(10 + x) = 90 + 9x
Your answer is B. 90 + 9x.
