Answer:
120 degrees
Step-by-step explanation:
Since the total degree measure of a circle is 360 degrees, if a part of it is 240 degrees, then the rest is 360-240=120 degrees. Hope this helps!
Answer:
Step-by-step explanation:
1) angle GLH = angle JLI. This is so because they are vertically opposite angles.
angle JLI = 30 degrees. Therefore,
angle GLH = 30 degrees.
2) The sum of angles at a point is 360 degrees. It means that
Angle HLI + angle JLI + angle KLJ + angle GLK + angle HLG. Therefore,
Angle HLI + 30 + 60 + 90 + 30 = 360
Angle HLI + 210 = 360
Angle HLI = 360 - 210 = 150 degrees
3) angle ILK = 60 + 30 = 90 degrees
Answer:The height of the building is 30ft
Step-by-step explanation:
Answer:
z = 7 and z = 69
Step-by-step explanation:
In the given figure, two lines are cut each other.
Here we have to use the following property.
If the two lines intersect each other, then the opposite sides are equal.
Therefore, 11x + 34 = 111
Now we have to find the value of x.
Solve for x.
11x = 111 - 34
11x = 77
Dividing both sides by 11, we get
x = 77/11
<u> x = 7</u>
Now we have to find the value of z.
Adjacent angles add upto 180 in a straight line.
Therefore, 111 + z = 180
Subtract 111 on both sides, we get
111 + z -111 = 180 - 111
<u>z = 69</u>
Therefore, z = 7 and z = 69
Hope you will understand the concept.
Thank you.
