Now,
<X + <Y + <Z = 180° ( The sum of the angle
of interior angle is 180°)
or, 32° + <Y + 78° = 180°
or, <Y = 180° - 110°
◆ <Y = 70°
I hope you understand...
Thank you ♥♥
I think it’s 98 square ft
Answer:
Area of the rectangle A = 32 x - 8
Step-by-step explanation:
<u><em>Explanation:-</em></u>
Given that the length of the rectangle(l) = 8x-2
Given that the width of the rectangle (w) = 4
Area of the rectangle = length × width
A = (8x - 2) × 4
A = 32 x - 8
<u><em>Final answer</em></u>:-
Area of the rectangle A = 32 x - 8
Answer: the cost of one shirt is $28
the cost of one sweater is $23
Step-by-step explanation:
Let x represent the cost of one shirt.
Let y represent the cost of one sweater.
Lonnie purchased three sweaters and two shirts for $130. It means that
2x + 3y = 130 - - - - - - - - -1
If the sale price of a shirt was five dollars less than the sale price of a sweater, it means that
x = y - 5
Substituting x = y - 5 into equation 1, it becomes
2(y - 5) + 3y = 130
2y - 10 + 3y = 130
2y + 3y = 130 + 10
5y = 140
y = 140/5
y = 28
x = y - 5 = 28 - 5
x = 23
Answer:
C (0, 9)
Step-by-step explanation:
First, X is reflected across the line x=2.
X(4, -7) becomes X'(0, -7).
Next, X' is reflected across the line y=1.
X'(0, -7) becomes X"(0, 9).
