Answer:
? = 7.45
Step-by-step explanation:
Since this is a right triangle, we can use trig functions
cos theta = adjacent side/ hypotenuse
cos 20 = 7 / ?
Multiply each side by ?
? cos 20 = 7
Divide each side by cos 20
? = 7/ cos 20
? =7.449244407
To the nearest hundredth
? = 7.45
Answer:
Okay, but doesn't this bring any trouble reading?
I’m pretty sure the answer is B because
8X- 4Y = -16 and it shows that in the equation of number B and if I’m wrong please correct me
Answer:
I actualy can't see
Step-by-step explanation:
Absolute value is just whatever number wether positive or negitive, and made positive.
This is because aboslust value means the distance from zero, and distance is always positive.
Answer:
The fourth pair of statement is true.
9∈A, and 9∈B.
Step-by-step explanation:
Given that,
U={x| x is real number}
A={x| x∈ U and x+2>10}
B={x| x∈ U and 2x>10}
If 5∈ A, Then it will be satisfies x+2>10 , but 5+2<10.
Similarly, If 5∈ B, Then it will be satisfies 2x>10 , but 2.5=10.
So, 5∉A, and 5∉B.
If 6∈ A, Then it will be satisfies x+2>10 , but 6+2<10.
Similarly, If 6∈ B, Then it will be satisfies 2x>10 , and 2.6=12>10.
So, 6∉A, and 6∈B.
If 8∈ A, Then it will be satisfies x+2>10 , but 8+2=10.
Similarly, If 8∈ B, Then it will be satisfies 2x>10. 2.8=16>10.
So, 8∉A, and 8∈B.
If 9∈ A, Then it will be satisfies x+2>10 , but 9+2=11>10.
Similarly, If 9∈ B, Then it will be satisfies 2x>10. 2.9=18>10.
So, 9∈A, and 9∈B.
