X= 48 is the correct answer. You can always plug in 48 back into the original equation and make sure it works.
48-23+84+48+23=180
Answer:
Angle of Regular polygon = 166.15° (Approx.)
Step-by-step explanation:
Given:
Regular polygon with 26 sides
Find:
Measure of each angle of Regular polygon
Computation:
Angle of Regular polygon = [(n-2)180] / n
where n = number of sides
Angle of Regular polygon = [(26-2)180] / 26
Angle of Regular polygon = [(24)180] / 26
Angle of Regular polygon = [4,320] / 26
Angle of Regular polygon = 166.15° (Approx.)
Answer:
128°
Explanation:
1 = 4 because of vertical angles are the same
4 = 5 because of alternate interior angles are the same
5 = 8 vertical angles
8 = 9 alternate interior angles
9 = 12 vertical angles
180° = 12 + 11
11 = 180° - 52°
angle 11 = 128°
Answer:
133, 79, 148 are ALL possible, so select 133 and 79
Step-by-step explanation:
Subtract 47 and 32 from 180 to find the third angle of the triangle (it is 101).
Then do 180-101 = 79
180-32=148
180-47=133
That tells you the exterior angle of each. Only two possible choices on your list.
First question:
When you bisect an angle, you create two new equal angles, both measuring half of the original angle. So, if the original angle was 52°, the two angles will be 52/2=26 degrees each.
Note: the picture is not very clear, and I'm not sure the original angle is 52°. It it's not, just divide by 2 whatever measure the angle is.
Second question:
Focus on triangles RQP and RSP:
- They are both right, because Q and S are right angles
- We are given QP=SP
- They share the side RP
So, they are congruent. This implies that angle SRP is 50° as well, and then
QRS = QRP+SRP = 50°+50°=100°
