Answer:
72cm
Step-by-step explanation:
A=a^2
p=4a
p=4√A=4x√324=72 cm
Answer : d. 438.5 ft
The diagram for the given statement is attached below.
Two sides AB and AC are equal so the angle B = angle C
WE know sum of three sides of a triangle = 180
angle A + angle B + angle C = 180
55 + B + C = 180
B + C = 180 -55 = 125
B and C are equal so we divide 125 by 2
angle B = 62.5 and angle C = 62.5
Now we apply sin law


150 * sin(55) = sin(62.5) * a
122.8728066 = sin(62.5) * a
a = 
a= 138.52 feet
To find perimeter we add all the sides
150 + 150 + 138.52 = 438.52 feet
Answer:
1.5 × 1011 m
Step-by-step explanation:
960 cups of alcohol (or 60 gallons)
360 gallons of water
240 cups of ammonia (or 15 gallons)
Take total and divide by 8 , so 1280 divide by 8 is 160. now multiply each amount by 160. *(remember there are 16 cups in a gallon . So you dived total amount of cups by 16 to convert it to gallons)
