There are three more angles with the same measure. A pair of corresponding angles and a pair of vertical angles.
For a segment AB, the coordinates of the middle point C are:
xc=(xa+xb)/2,
yc=(ya+yb)/2.
Now, you know points A and C. Thus we get:
xb=2×xc-xa
yb=2×yc-ya
With numerical values:
xb=2×2-(-1)=4+1=5
yb=2×3-(-5)=6+5=11
Answer: B(5, 11)
The equation used to find the surface area of a sphere is 4 x pi x r^2. The surface area of the sphere with a diameter of 16 inches would be
4 x 3.14 x 8^2 = 803.84. Therefore, the surface area of a sphere with a diameter of 16 inches would be 804 square inches. (rounded the decimal)
Answer:
The required value of x = 28
The required value of y = 32
Step-by-step explanation:
The given two equations are :

Now, we need to solve both the equations and find out the required values of both the unknowns x and y.
Solving equation (1) to obtain value of x. We have,

Solving equation (2) to obtain value of y. We have,

Hence, The required value of x = 28
And The value of y = 32
