Angle A and angle b are complementary angles. If m angle A=4x+6 and m angle b=4x-4 then find the measure of angle A

Pavlova-9 [17]

Answer:

Step-by-step explanation:

∠A and∠B being complementary means m∠A+m∠B=90°

m∠A = (4x+6)° and m∠B = (4x+4)°

so:

4x+6 + 4x+4 = 90

8x + 10 = 90

8x = 80

x = 10

m∠A = (4•10+6)° = 46°

If a line segment contains one endpoint at (2,3) and has a midpoint of (-2,6) what is the second endpoint of the line segment

olchik [2.2K]

Answer:

Step-by-step explanation:

The coordinates of the midpoint M are the average of the coordinates of the two endpoints:

$M_x = \dfrac{2+x}{2},\quad M_y = \dfrac{3+y}{2}$

Plug the known coordinates of the midpoint:

$-2 = \dfrac{2+x}{2},\quad 6 = \dfrac{3+y}{2}$

Solve for x and y:

$-4 = 2+x,\quad 12 = 3+y$

$x=-6,\quad y = 9$
