2+a / 2 = 4 and b+6 /2 = 10
2+a=8. and. b+6 = 20
a=6. and. b=14
(a,b) , the other endpoint, is thus (6,14)
Answer:
18
Step-by-step explanation:
since you want the difference in scores, you want to take the absolute value of the difference
9 - (-9) = 9+9 = 18
Answer:
B) 25°
Step-by-step explanation:
Assuming the quadrilateral is the one shown in the picture attached, then a triangle ADC is form, where m∠ADC = 125° and m∠1 = 30°. The addition of the three angles of a triangle is equal to 180°, so:
m∠ADC + m∠1 + m∠2 = 180°
Replacing with the known values and isolating m∠2 we get:
125° + 30° + m∠2 = 180°
m∠2 = 180° - 125° - 30°
m∠2 = 25°
