All of the angles add up to 360 degrees.
180(4-2) = 360
9x+1+5x-12+8x+61
Add up all the like terms
22x+50= 360
x=14.1
We are going to add up all of the angles together and subtract them by 360 in order to find the measurement of the missing angle.
Angle C: 9(14.1) + 1 = 127.9
Angle D: 5(14.1) - 12 = 58.5
Angle A: 8(14.1) + 61 = 173.8
All of these angles add up to 360
This means that angle D is 0 degrees since all of the other angles already add up to 360.
<u>Answer</u>
0 degrees
Answer:
f(x)= -4x
Step-by-step explanation:
Step-by-step explanation:
Area of shaded =Area of Outer rectangle - Area of Inner rectangle.
Area of inner rectangle = L× B.
L=18
B=11
Area of inner rectangle = 18×11
=198m^2
To find the full breadth of the outer rectangle
=2 in +11 + 2 in
=15
To find the full length of the outer rectangle
=2 in + 18 + 2 in
=22
Area= 22 × 15
Area = 330m^2
Area of shaded portion = 330 - 198
=132m^2
Answer:
d)
Step-by-step explanation:
i¹= i
i²= -1
i³= -i
i⁴= 1
i¹²⁴= i^(124 +0)
i^124 . i^0
i^(4×31) . i^0 = 1³¹. i^0
1.i^0= i^0
= 1
a) i^179= i^(176+3)
i^176 . i³ = i^(4×44) . i³
1⁴⁴. i³ = 1. i³
= -i
b) i^582 = i^(580 + 2)
i^580 . i²= i^(4×145) . i²
1^145 . i²= 1.i²
= -1
c) i^165= i^(164+1)
i^164 . i¹ = i^(4×41) . i¹
1⁴¹ . i¹ = 1.i
= i
d) i^740= i^(740+0)
i^740 . i^0 = i^(4×185) . i^0
1^185 . i^0 = 1. i^0
= 1
i¹²⁴= i^740 = 1
Answer:
A). Scale factor =
B). Length of the unknown side = 2.75 feet
Step-by-step explanation:
Part A
Since, the large rectangle was scaled by a scale factor 'k' to form the smaller rectangle,
Scale factor =
=
=
=
Part B
Scale factor =
Therefore, side length of the unknown side = = 2.75 feet
