Answer:
x = 15°
y = 59°
Step-by-step explanation:
Angles at a right angle add up to 90°
41 + y = 90
y = 90 - 41
y = 59°
Angles in a triangle add up to 180°
41 + (2x - 9) + 7x + 13 = 180
41 + 13 - 9 + 2x + 7x = 180
45 + 9x = 180
9x = 180 - 45
9x = 135
x = 135/9
x = 15°
Answer: A)
Explanation: 10-3=7
5 ten is equal to 50.
So, then what is 50 + 50
100
(-2,3) and (10,3)
Midpoints are quite easy once you know the rule. The coordinates of the midpoint are just the average of the coordinates of the two points...
The midpoint of this lines is:
((-2+10)/2, (3+3)/2)
(8/2, 6/2)
(4, 3)
