Answer:
x = 80 degrees
Step-by-step explanation:
First look at the upper triangle. There are two 65 degree angles there, along with two equal sides. The angles must sum up to 180 degrees. Therefore:
2(65) + x = 180; thus, the value of x is 50 degrees.
Next, recognize that the vertical angles in the middle of the diagram are equal and are 50 degrees each. Thus, the smaller triangle has two 50-degree angles. Again we sum up the angles, obtaining 50 + 50 + x = 180, or x = 80 degrees

17.2%
16.4%
15.7%
17.5%
Answers
Answer:
15.7%
Step-by-step explanation:
Experimental probability is the probability of something that is determined by doing an experiment.
To find the probability, divide the number of rolling a one and add all the occurrences of every other result.
So,
42 / (42 + 44 + 45 + 44 + 47 + 46) =
42 / 268 =
0.156716 =
15.6716
Rounded to the nearest tenth, the probability of rolling a one would be 15.7%.

Answer:
x = 9cm
using sine rule
a/sine(A) = b/sine(B)
a= x; A= 64° ( alternating angles)
b= 10 cm ; B = 90°
x/sine(64) = 10/sine(90)
x= {10 × sin(64)}/ sin 90
x = 9cm

The range of the given data is 34.
The width of the class interval in the given data is 4.
What is the range?
Range is the difference between the highest and lowest values of a set of observations
Range =Upper-class boundary of the highest interval – Lower class boundary of the lowest interval
79 - 45 = 34
What is the class width?
The class width is the difference between the upper bound and lower bound.
Class width : 49 - 45 = 4
