The measures of all of the interior angles of the triangle are 70 degrees, 70 degrees and 40 degrees
Solution:
Given that exterior angle of triangle is 140 degrees
The exterior angle of a triangle is equal to the sum of the measures of the two non-adjacent interior angles
Given that adjacent angles are congruent
Let one of the non adjacent interior angles be "x"
x + x = 140
2x = 140
x = 70
So the two interior angles are 70 degrees and 70 degrees
Let us find the third interior angle
The angle sum property of a triangle states that the interior angles of a triangle always add up to 180 degrees
70 + 70 + third angle = 180
third angle = 180 - 70 - 70
third angle = 180 - 140
third angle = 40 degrees
Thus the measures of all of the interior angles of the triangle are 70 degrees, 70 degrees and 40 degrees
B 1436.03 cm3
C 1975.43 cm3
D 11,494.04 cm3
Answer:
b
Step-by-step explanation:
Answer:
B. 1436.03 cm^3
Step-by-step explanation:
What you do is use the formula of the volume of a sphere which is
v=4/3*3.14*r^3.
The r represents radius and the radius is 7 which is half the diameter.
So you will plug 7 into the formula.
V=4/3*3.14*7^3.
V=1436.03 cm^3 which is your answer.

924 people rode the rollercoaster.
The answer is option (C).
The percentage means the required value out of 100.
It is calculated by dividing the required value by the total value and multiplying by 100.
The percentagechange is also calculated using the same method.
In percentage change, we find the difference between the values given.
Example:
Required percentage value = a
total value = b
Percentage = a/b x 100
We have,
To find the number of people who rode the roller coaster,
We can multiply the total number of people at the park by the percentage who rode the roller coaster:
So,
The number of people who rode the roller coaster.
= 77% × 1,200
= 77/100 x 1200
= 924
Therefore,
924 people rode the rollercoaster.
