If you already stated it's greater than 60, why state it's greater than 57? Unless you are saying the number is greater than 57 and less than 60... The answer would be 59.
Answer:
Interior = 60°
Exterior = 120°
Step-by-step explanation:
A triangle has 180° in total.
We have 2 angles, 70 and 50
70 + 50 = 120
For Angle U, we do 180-120 = 60
So the interior angle is 60°
A line is straight and is 180°
With angle U being 60°, and being on a straight line, 180-60 = 120
So exterior angle is 120°
10^2+8^2-7^2/(2*10*8)
= 115/160 = 0.71875 round off to 0.72
Where’s the model? If it says choose a model, there should be a model
Since the dimension of the scale model is fourth of dimensions of the room, divide by 4 the given dimensions.
new dimensions:
= 18 ft / 4 = 9/2 ft
= 16 ft / 4 = 4 ft
The area is calculated by multiplying the dimensions,
Area = (9/2 ft)(4 ft) = 18 ft²
Therefore, the area of the scale model is equal to 18 ft².
