Answer:
y = 70°
Step-by-step explanation:
4x - 50 and 2x + 30 are equal, because they are corresponding angles
4x - 50 = 2x + 30
4x = 2x + 80
2x = 80
x = 40°
The angle below 2x + 30 = y, because they are vertical angles
Since we know what x is, we can substitute x from 2x + 30
And since two angles that take up a line are 180°, we can add them
2(40) + 30 + y = 180
80 + 30 + y = 180
110 + y = 180
y = 180 - 110
y = 70

Answer:
27
Step-by-step explanation:
find square root of 81 and multiply by 3
9 x 3 = 27
X= 13.5
Every triangle equals 180 degrees. 23+23= 46. 46 - 1= 45. Then you solve the equation 10x+45=180 which would equal, 13.5.
Answer:
Option A -8/3
Step-by-step explanation:
The complete question in the attached figure
we know that
Sasha started at sea level and has hiked down to the fourth rest station.
Remember that sea level is 0.
Sasha takes a break at the rest stations every 2/3 of a mile.
That means-----> Sasha is down 4 times 2/3
But the answer will be in negative as she is below 0.
therefore
Sasha’s elevation now is -8/3 miles below sea level.
