Find two numbers if....
Their sum is -7 and their difference is 14
Answers
Let
a------------> first number
b------------> second number
we know that
a+b=-7--------> a=-7-b----------> equation 1
a-b=14--------> equation 2
I substitute 1 in 2
(-7-b)-b=14-------------> -7-b-b=14----------> -7-2b=14-------> 2b=-7-14
2b=-21---------> b=-10.5
a=-7-b-------> a=-7-(-10.5)-----> a=-7+10.5------> a=3.5
the answer is
the two numbers are
a=3.5
and
b=-10.5

Given cot A = 63/16 and that angle A is in Quadrant , find the exact value of sin A in simplest radical form using a rational denominator.
Answers
Answer:
sin(A) = 16*Cos(A)/63
Step-by-step explanation:
You didn't state what quadrant it was in.
The sine of angle A is 16 / 65
What is the sine of an angle?In a right-angled triangle, the sine of an angle is equal to the ratio of the side opposite to the angle (also called perpendicular) and hypotenuse.
Give that, cot A = 63/16 and that angle A is in Quadrant, (refer to the figure attached)
Since, we know that, cotangent of an angle is ratio of adjacent side to opposite side.
Using Pythagoras theorem, we get,
63²+16² = 4255
√4225 = 65
Therefore, the hypotenuse = 65
sine of an angle = opposite side / hypotenuse
sinA = 16 / 65
Hence, the sine of angle A is 16 / 65

A 135.8 foot wire is attached to the top of the tower. If the wire is attached to the ground 30 feet from the bottom of the tower, then what angle does the wire make with the ground?
Answers
Answer:
77.23°
Step-by-step explanation:
Given that,
A 135.8 foot wire is attached to the top of the tower.
The wire is attached to the ground 30 feet from the bottom of the tower.
It means,
If we consider a triangle such that hypotenuse is 135.8 foot and base is 30 feet, it means we can use the trigonometry as follows :
[tex]\cos\theta=\dfrac{B}{H}\\\\\cos\theta=\dfrac{30}{135.8}\\\\\theta=77.23^{\circ}[/tex]
So, the angle the wire make with the ground is equal to 77.23°.
