Find the values for x and y

Mathematics

Answer:
x = 55; y = 70

Explanation:
According to the image provided, all three angles should be the same. This makes it much easier to solve the problem. It is necessary to remember that a triangle equals a total of 180 degrees. Since there are three angles, we shall divide 180 by three.

180/ 3 = 60

Now we will use 60 to help us solve for the values of x and y.

Step 1 - Step up your equation to find y

y - 10 = 60

Step 2 - Add 10 to both sides of the equation

y - 10 = 60
y - 10 + 10 = 60 + 10
y = 70

So, y = 70

Step 4 - Set up your equation to find x

x + 5 = 60

Step 5 - Subtract 5 from both sides of the equation

x + 5 = 60
x + 5 - 5 = 60 - 5
x = 55

So, x = 55

Answer:

x = 55

y = 70

Step-by-step explanation:

Since all three sides are equal, as indicated by the lines on the sides, all three angles are equal

Since a triangle is equal to 180 degrees

180/3 = 60

Each angle is 60 degrees

x+5 = 60

Subtract 5 from each side

x +5-5 = 60-5

x = 55

y-10= 60

y-10+10 = 60+10

y= 70

A kite flying in the air has an 7-ft line attached to it. Its line is pulled taut and casts a 5-ft shadow find the heights of th
Stels [109]

The height of the kite is 4.89 feet

Explanation

The length of the line attached to the kite=7 feet

The length of the shadow that is cast on the ground=5 feet

the system forms a right angled triangle where the taught string of the kite is the hypotenuse, the shadow is the base and the height of the kite above the ground is the height.

H=7 feet

b=5 feet

using pythagoras theorem

h^2+b^2=H^2\\h^2=H^2-b^2\\h^2=7^2-5^2\\=49-25\\=24\\h=\sqrt{24\\} =2\sqrt{6} \\=4.89 feet

The kite is 4.89 feet above the ground

Can someone please help me? I don't understand this problem. How would they be the same???
musickatia [10]
Area of rectangle = 15 x 8
                           =120

area of parallelogram = 8 x 15 
                               =120
so, they have the same area, because the length of a rectangle is the same as the height of a parallelogram and also for the base.
