The answer to the problem it 54. because 378 divided by 7 =54
Answer:
26, 68 and 84
Step-by-step explanation:
Let the angle that is three times smaller than another be X.
Since the angle sum of a triangle is 180 degrees, we can form the following equation:
X + 3X + (3X- 16) = 180
Now we can simplify this equation:
7X - 16 = 180
7X = 196 (add 16 to both sides)
X = 196/7
X = 28
Therefore, the smallest angle is 28 degrees.
And from here we can figure out the other angles as they are 3x28 and 3x28 - 16.
So the three angles are 28 degrees, (3x28-16) 68 degrees, and (3x28) 84 degrees.
Answer:
D
Step-by-step explanation:
in this case, because it is being dilated by a factor of 2 this means that figure A´B´C´ will be double the size of its pre-image ABC.
each side will now be its double which means:
side A´C´= 10
side B´C´= 6
and side A´B´= 8
since the figure is only increasing its sides the angles of the right triangle remain the same.
<A= 37 degrees
Answer:
113 ft²
Step-by-step explanation:
π = 3.14
r = 6
Use the formula for the area of a circle:
A = πr²
A = 3.14*6²
A = 3.14*36
A = 113.04
A = 113
Hope this helps :)
Answer:
Step-by-step explanation:
Let age of each twin be x
let age of sister be s
So we can write:
x + 4 = s
The product of the 3 siblings ages is 3482 more than sum. We can write:
This can be simplified as:
We replace s with "x + 4" and solve:
<u>Note:</u> To solve this cubic, we used technology
Thus, we can say the twins are 14 years old
