Let the length of one side of the original square be a.
The length of one side of the new square is (a+7) feet,
the area of the second square is
taking the square root of both sides:
a+7=11
a=4
Answer: 4 feet
Answer:
13
Step-by-step explanation:
4 + 9
[ 9 + 2 = 11 ]
[ 11 + 2 = 13 ]
Answer:
An angle can be formed when two rays meet at a common point. The rays are the sides of the angle. The point of the end of two rays is called the vertex.
Step-by-step explanation:
Answer:
x=2
Step-by-step explanation:
There are 3 trigonometric ratios:
Sine = opposite/hypotenuse,
Cosine = adjacent/hypotenuse and
tangent = opposite/adjacent
Since in the question we have not been given the hypotenuse, we calculate it first.
So, hypotenuse = √(12²+5²) = √(144+25) = √169 = 13.
Now we can find the trigonometric ratios;
Sin A = Cos B = 5/13
Sin B = Cos A = 12/13
Tan A = 5/12
Tan B= 12/5
