Answer:
Its actually really easy.
Y is = to 76 degree (Vertically Opposite Angle)
The same way x = z (Vertically Opposite Angles)
So as y = 76 and given angle also 76 we'll add them. You should get 152. Now we know x = z. And we also know angles around a point add up to 360. So 360 - 152 gives 208. Since there are two angles we'll divided them by 2. So you now have 104
Given angle : 76
Y : 76
X : 104
Z : 104

Answer:
The dimensions of the rectangle are length = 7cm and width = 6cm.
Step-by-step explanation:
In order to solve for the dimensions, you will need to set up two equations in order to solve for the missing variable. Given the information that the length is 5 cm less then twice it's width, using 'L' for length and 'w' for width we get the following equation: L = 2w - 5. Perimeter is the sum of all the sides, or in the case of a rectangle P = 2w + 2L. We can then use our expression for 'L' in our perimeter formula: 26 = 2w + 2(2w - 5). First, using the distributive property we get: 26 = 2w + 4w - 10. Next, we combine like terms: 26 = 6w - 10. Then, we use inverse operations to isolate the variable: 26 + 10 = 6w - 10 + 10 to get 36 = 6w, divide both sides by 6 to get w = 6. Lastly, plug in the value of 'w' to 'L': L = 2(6) - 5 or L = 7.
Move 12 to the other side, making it negative
h=31-12
h=19
