Answer:
66
Step-by-step explanation:
subtract each external angle by 180 to find the interior angle.
Since you know that all of the interior angles add up to 540 because 180(n-2)
with n is how many sides in the polygon
so 180(5-2)=540
now take each value and subtract it by 180
180-(45)=135
180-(40)=140
180-(x)=180-x
180-(77)=103
180-(2x)=180-2x
135+140+180-x+103+180-2x=540
738-3x=540
x=66
hope that helps :)

whats the ninth term of 25 20 15 10 5
Answers
Given:
The sequence is 25, 20, 15, 10, 5.
To find:
The ninth term of the given sequence.
Solution:
We have,
25, 20, 15, 10, 5
It is an AP because the difference between two consecutive terms are same.
Here,
First term (a) = 25
Common difference (d) = 20-25
= -5
The nth terms of an AP is
[tex]a_n=a+(n-1)d[/tex]
Where, a is the first term and d is the common difference.
Putting a=25, n=9 and d=-5 to get the 9th term.
[tex]a_9=25+(9-1)(-5)[/tex]
[tex]a_9=25+(8)(-5)[/tex]
[tex]a_9=25-40[/tex]
[tex]a_9=-15[/tex]
Therefore, the ninth term of the given sequence is -15.

The perimeter of a rectangular
Sheet is 120 cm. If the length is 40 cm, find its breadth.
Also find its area.
Answers
Answer:
Breadth = 20 cm
Area = 800[tex]cm^{2}[/tex]
Step-by-step explanation:
Perimeter = 120 cm
length = 40 cm
Perimeter = 2 ( L + B )
L - length B - Breadth
120 = 2 ( 40 + B )
120 = 80 + 2B
2B = 120 - 80
2B = 40
B = [tex]\frac{40}{2}[/tex] = 20 cm
Breadth = 20 cm
Area of a reactangle = Length × Breadth
= 40 × 20
= 800[tex]cm^{2}[/tex]

Kevin is 3 times as old as
Daniel. 4 years ago, Kevin was 5 times as old as Daniel.
How old is Daniel now?
Answers
Answer:
Daniel is 8 years old now.
Step-by-step explanation:
From the word problem we can make the following two equations:
Let "K" be Kevin's age now and let "D" be Daniel's age now, then...
K = 3D
K - 4 = 5(D - 4)
Now we substate the value of K, and get...
K - 4 = 5(D - 4)
3D - 4 = 5(D - 4)
3D - 4 = 5D - 20
3D - 5D = - 20 + 4
- 2D = - 16
D = 8
Therefore Daniel is 8 years old now.

70, 000 grams
Step-by-step explanation:
first convert grams to kilograms
there are 1,000 grams in a kilogram so multiply the 200 kg by 1,000
so
200 * 1000 = 200,000
200,000 grams of vegetables is what he started with
then you have to multiply that by the 35% that he sold
so
200,000 * 35% = 70,000
he sold 70,000 grams of vegetables by noon

A jet airliner, flying initially 300 mi/hr due
east, suddenly enters a region where the
wind is blowing 100 mi/hr, pushing the
aircraft in the direction 30° north of east.
What is the resultant speed of the aircraft?
Answers
Answer:
389.82 mi/hr
Step-by-step explanation:
For us to find the resultant speed of the aircraft, we will simply add the vector components of the wind and the vector velocity of the aircraft to get;
V = v_xi^ + v_yj^
Now,
v_xi^ = (300 + 100cos30°)i^
v_yj^ = (100 sin 30°) j^
This gives;
v_xi^ = 386.6 i^
v_yj^ = 50 j^
Thus;
V = 386.6 i^ + 50 j^
Resultant velocity is;
|V| = √(386.6² + 50²)
|V| = √151959.56
|V| = 389.82 mi/hr
