For U= (2,3,4,5,6,7,8), X=(2,3,4,5), state X'=
tatiyna
Answer:
X' = {6,7,8}
Step-by-step explanation:
X' is the set that contains the elements that are in set U bot NOT in set X.
Answer:
Step-by-step explanation:
<u>Since ΔFHG ≅ QRC, the corresponding angles are congruent:</u>
- ∠F = ∠Q
- (2x + 10)° = (3x + 1)°
- 3x - 2x = (10 - 1)°
- x = 9°
<u>Then, the angle Q measures:</u>
2.5 x (9+12) = 52.5
Hope that helps!
Answer:
=14
Step-by-step explanation:
In a rhombus, opposite angles are equal.
In the one provided in the question, 5x° is opposite the angle 70°
Let us equate the two.
5x=70
x=70/5
=14°
The value of x in the figure is 14°
Answer:
Both fireworks will explode after 1 seconds after firework b launches.
Step-by-step explanation:
Given:
Speed of fire work A= 300 ft/s
Speed of Firework B=240 ft/s
Time before which fire work b is launched =0.25s
To Find:
How many seconds after firework b launches will both fireworks explode=?
Solution:
Let t be the time(seconds) after which both the fireworks explode.
By the time the firework a has been launched, Firework B has been launch 0.25 s, So we can treat them as two separate equation
Firework A= 330(t)
Firework B=240(t)+240(0.25)
Since we need to know the same time after which they explode, we can equate both the equations
330(t) = 240(t)+240(0.25)
300(t)= 240(t)+60
300(t)-240(t)= 60
60(t)=60

t=1
