Answer:
D
Step-by-step explanation:
If you put a line down the middle of d and fold it in half it will be the same on both sides.
Answer: Angle A = 120° and angle C = 45°
Step-by-step explanation: The first thing to note at the back of our minds is that the sum of the interior angles of a triangle equals 180°. Given that the three angle are available, we can start by adding them all together. Hence,
{12x + 12} + 15 + {3x + 18} = 180
12x + 12 + 15 + 3x + 18 = 180
By collecting like terms, we arrive at,
12x + 3x + 12 + 15 + 18 = 180
15x + 45 = 180
Subtract 45 from both sides of the equation
15x = 135
Divide both sides of the equation by 15
x = 9
At this point, we can now substitute for the value of x = 9 in the expressions representing angles A and C.
Angle A = 12x + 12
= 12(9) + 12
= 108 + 12
= 120
Angle A = 120°
Angle C = 3x + 18
= 3(9) + 18
= 27 + 18
= 45
Angle C = 45°
Answer:
A) 180+15x=500
B) 21 people.
Step-by-step explanation:
$180
so 500-180 is 320.
320/15 is 21 1/3
So, Ms. Douglas can take 20 students and herself :)
Part A:
180+15x=500
180-180+15x=500
15x=320
x=21 1/3, so Ms. Douglas can afford to take 21 people,, but one of them is herself.
Hope this helps pls hit the crown :D
