Find the measure of A as indicates in the picture.

mina [271]

Answer:

m∠A = 58°

Step-by-step explanation:

In ΔABC,

m∠BAC = (x + 63)°

m∠ABC = (x + 96)° [Vertically opposite angles]

m∠ACB = (180° - 149°)

= 31°

By triangle sum theorem,

m∠ABC + m∠ACB + m∠BAC = 180°

(x + 96) + 31 + (x + 63) = 180°

2x + 190 = 180

2x = -10

x = -5

Therefore, measure angle A = (x + 63)

= -5 + 63

= 58°

Points A and B are located in a standard (x,y) coordinate plane. If A has coordinates (4,-4) and B has coordinates (0,8), what a

dimulka [17.4K]

the easiest way I find a midpoint of two points is the midpoint theorem, here it is:

$\frac{x1+x2}{2} , \frac{y1+y2}{2}$

For x and y plug in the two coordinates given, (4,-4) & (0,8)

so once you plug the numbers into the equation you would get:

(2,2)
