Answer:
122 degrees
Step-by-step explanation:
*A pentagon has a total of 540degrees
1st step: take all of the degrees and add them up:
105 + 90 + 86 + 137 = 418
2nd step: subtract the sum from 540:
540 - 418 = 122
The missing angle is 122 degrees
Answer:
∠ C = 122°
Step-by-step explanation:
The sum of the interior angles of a polygon is
sum = 180° (n - 2) ← n is the number of sides
Here n = 5, then
sum = 180° × 3 = 540°
Sum the given angles and equate to 540°
∠ C + 137° + 86° + 105° + 90° = 540 , that is
∠ C + 418° = 540° ( subtract 418° from both sides )
∠ C = 122°

What percent of the time will the point be in the shaded region
Answers
Answer:
29.4%
Step-by-step explanation:
the whole cirlce is 360 degrees which means 100%
to find the percentage of the shaded area, multiply the degrees by 100
⇒ 10.6 x 100 = 10600
then take the product and divide by 360
⇒ 1060 ÷ 360
⇒ 29.44
round to the nearet tenth of a percent

Answer:
choice 2) angle DOC = 145 degrees
Step-by-step explanation:
angle ABD = 1/2(30 degree arc) = 15 degrees because of the inscribed angle theorem.
angle AOB = 180 - 20 - 15 = 145 degrees
angle DOC = angle AOB because it is a vertical angle to 145 degrees.

This table shows information from a survey about the type of coffee people prefer and whether they like it hot or cold.
of the people who prefer mocha, the relative frequency of them preferring it cold is 0.32
of the people who prefer hot coffee, the relative frequency of them preferring a latte is 0.22
The type of coffee that has the highest percentage of people who prefer it cold is a. regular b. mocha c. latte
the answer is not cappuccino!
Answers
Answer:
0.32
.22
regular (capuccino is incorrect)
Step-by-step explanation:
in the mocha column 25 people prefer hot and 12 people prefer cold are equal to 37 people. 25+12=37
relative frequency of preferring cold is 12. 12÷37 = .32
In the hot column 11, 25, 19, 30 people are combined for total of 85 people who prefer hot coffee. 11+25+19+30=85
relative frequency of preferring a latte is 19: 19÷85 = .22
combine regular column for 17 ÷ 28 = .61
combine mocha column for 12÷40 = .30
combine latte column for 20÷39 = .51
combine cappucino column for 27÷57 = .47
The type of coffee that has the highest percentage of people who prefer it cold is regular. (if you combine only the cold column you will end up with cappuccino which is wrong.)

Answer:
Option A. x = 8
Step-by-step explanation:
Please see attached photo.
From the attached photo,
we shall determine the value of y. This can be obtained by using pythagoras theory as illustrated below:
(√80)² = 8² + y²
80 = 64 + y²
Collect like terms
80 – 64 = y²
16 = y²
Take the square root of both side
y = √16
y = 4
Finally, we shall determine the value of x. This can be obtained as follow:
From the attached photo,
x = 2y
but:
y = 4
Therefore,
x = 2y
x = 2 × 4
x = 8

In isosceles triangle JKL, JK KL. If the measure of
angle J is 47°, find the measure of angle K.
*Note: Do NOT include the degree in your answer.
Answers
Answer:
86
Step-by-step explanation:
Since ∆JKL is an isosceles triangle, it's base angles (<L and <J) would be equal to each other.
<L is opposite to side JK, <J is opposite to side KL.
m<J is given as 47°. Therefore,
m<L = m<J = 47°
m<L = 47°
m<J + m<L + m<K = 180° (sum of triangle)
47° + 47° + m<K = 180° (substitution)
94° + m<K = 180°
m<K = 180° - 94°
m<K = 86°

= -3x² (2x+4)
= -6x³ - 12x²
b). f(g(-1))

Answer:
2.4 cm
Step-by-step explanation:
We know the length of segment AB and the length of segment BC. To find their midpoints, we can divide their length by 2.
Let's find the midpoint of AB.
Segment AB: 10 cm Midpoint of AB: 10/2 = 5 cmNext let's find the midpoint of BC.
Segment BC: 5.2 cmMidpoint of BC: 5.2/2 = 2.6 cmIn order to find the difference between these midpoints, we can subtract the midpoint of AB by the midpoint of BC.
5 cm - 2.6 cm = 2.4 cmTherefore, the difference between the midpoints of AB and BC is 2.4 cm.
