Answer:
x<=10
Step-by-step explanation:
2x<= 32-12
2x<= 20
x<= 20/2
x<= 10
<span>(14.2a + 9.8b) - (13.1b - 0.2a) - (3.7a + 4.8b)
</span>14.2a + 9.8b - 13.1b + 0.2a - 3.7a - 4.8b
(14.2a + 0.2a - 3.7a) + (9.8b - 13.1b - 4.8b)
10.7a - 8.1b
Answer:
since the room is rectangular and has 4 sides
2 sides have the same length
18*2= 36m
80*2=160m
then add the sums...
the answer is 196 meters
Step-by-step explanation:
Hello there! I can help you! So what we are looking for is the value of x. To find the value of x, we can write and solve an equation. Set it up like this:
4x + 28 = 180
This is because the sum of the angles for a triangle is 180°. We combine the like terms to get 4x and subtract 6 from 34 to get 28. First off, let's subtract 28 from both sides. 28 - 28 cancel out. 180 - 28 is 152. That simplifies into 4x = 152. Now, divide each side by 4 to isolate the x. 4x/4 cancels out. 152/4 is 38. There's a possible value of x. Let's plug the value in and see if it works. 38 * 2 is 76. 76 - 6 is 70. 38 + 34 is 72. 70 + 72 is 142 and 142 + 38 is 180. 180 = 180. There. x = 38. Here are the answers for the angle measurements:
(x + 34) = 72°
(2x - 6) = 70°
x° = 38°
Answer:
123°, 57°, 123°
46°, 90°
Step-by-step explanation:
28. m∠L=57° ⇒ opposite angle m∠J=m∠L=57°
m∠M= m∠K= 180° -m∠L= 180° - 57°= 123°
29. m∠W= m∠X= 90°
m∠Y= 180° -m∠W= 180° - 134°= 46°
