Answer:angle A = 21 degrees

Angle B = 80 degrees

Angle C = 79 degrees

Step-by-step explanation:

The sum of the angle in a triangle is 180 degrees. This means that in triangle ABC,

Angle A + angle B + angle C = 180 degrees. Therefore,

2x + 7 + 10x + 10 + 8x + 23 = 180

2x + 10x + 8x + 7 + 10 + 23 = 180

20x + 40 = 180

20x = 180 - 40 = 140

x = 140/20 = 7

Therefore,

Angle A = 2x + 7 = 2 × 7 + 7 = 14 + 7 = 21 degrees

Angle B = 10x + 10 = 10 × 7 + 10 = 70 + 10 = 80 degrees

Angle C = 8x + 23 = 8 × 7 + 23 = 56 + 23 = 79 degrees

Another question for math. ill give mad points, the question is in attachment
yulyashka [42]
For this case we have the following points:
 y = (- 2, 5)
 z = (1, 3)
 Therefore, the vector yz is given by:
 yz = z - y = (1, 3) - (-2, 5)
 yz = ((1 - (- 2)), (3-5))
 yz = ((1 + 2), -2)
 yz = (3, -2)
 Then, the magnitude is given by:
 lyzl = root ((3) ^ 2 + (-2) ^ 2)
 lyzl = root (9 + 4)
 lyzl = root (13)
 Answer:
 
yz = (3, -2)
 lyzl = root (13)
