Answer:
Step-by-step explanation:
a + 143 = 180 {Linear pair}
a = 180 - 143
a = 37
37 + 93 + b = 180 {Angle sum property of triangle}
130 + b = 180
b = 180 - 130
b = 40
c + b = 90
c + 40 = 90
c = 90 - 40
c = 50
d + 120 = 180 {Linear pair}
d = 180 - 120
d = 60
? = 60 + 40 {Exterior angle property of triangle}
? = 100
For a standard double six set domino and starting with a double six,
6|6 followed by 6|5 followed by 5|5 followed by 5|4 followed by 4|4 followed b 4|4 followed by 4|3 followed by 3|3 followed by 3|2 followed by 2|2 followed by 2|1 followed by 1|1 followed by 1|0 followed by 0|0
The last number is 0
Answer:
let the grade points be a,b,c
a+b+c=258
b=c+10( since she noticed that on tests two and three,she scored 10 points fewer).

Step-by-step explanation:
The sine of an angle is equal to the cosine of that angle minus 90 degrees, and vice versa. Since 65=90-25, the cosine of 25 is equal to the sin of 65. If this is unclear please PM me or comment, and I can help more!
