Diskette morning my dear dear sister I hope your day off I will check for you and you please please Shia
Answer:
see explanation
Step-by-step explanation:
∠ 1 and ∠ 2 are adjacent angles and are supplementary, sum to 180° , so
5x + x + 54 = 180 ← equation to solve to find x
6x + 54 = 180 ( subtract 54 from both sides )
6x = 126 ( divide both sides by 6 )
x = 21
Then
∠ 1 = 5x = 5 × 21 = 105°
∠ 2 = x + 54 = 21 + 54 = 75°
16 desserts 8+8+8+8+8= 40 so 2/5 of 40 is 16
Hope this help Have a great day.
Answer:
x = 3.5
Step-by-step explanation:
2x + 5 = 12
2x = 7
x = 3.5
Hope that helped!
Answer:
z = 3/2 (turn it into decimal if required)
Step-by-step explanation:
Let the angle be x.
Taking x as reference angle
cosx = b/h
or, cosx= z/3
Again taking x as reference angle for the bigger triangle,
cosx = b/h
or, cosx = 3/6
or, cosx = 1/2
so, x = 60
Now,
As we found out,
cosx = z/3
or, cos60 = z/3
or, 1/2 = z/3
or, 3 =2z
so, z = 3/2
