Step-by-step explanation:
Answer:
G = 78°
H = 98°
Step-by-step explanation:
Opposite angles in a cylic quadrilateral are supplementary. Therefore:
G + E = 180°
Substitute
8x + 1 + 11x + 8 = 180°
Add like terms
19x + 9 = 180°
19x + 9 - 9 = 180° - 9
19x = 171
19x/19 = 171/19
x = 9
G = 8x + 1
Plug in the value
G = 8(9) + 1 = 73°
H + F = 180° (opposite angles of a cyclic quadrilateral is equal?
Plug in the values
6y - 4 + 5y - 3 = 180°
Add like terms
11y - 7 = 180
11y = 180 + 7
11y = 187
y = 187/11
y = 17
H = 6y - 4
Plug in the value of y
H = 6(17) - 4
H = 98°
Answer:
5 cm
Step-by-step explanation:
The two sides of the rectangle are 8 and 2, and the same can be said for the other two sides. This means to get the perimeter of the rectangle, we add:
8, 8, 2, and 2, which gets us 20.
This means that the perimeter of the square is also 20. Now we have to find the value of the sides.
To do this we can say that every side of the square is equal in length, and there are 4 sides.
All we need to do is take the perimeter, 20, and divide it by 4, which will give us our answer of 5 cm.
