Answer:
x = 9
Step-by-step explanation:
Given : A triangle with angle 39 degree.
To find : Find the value of x to the nearest tenth.
Solution : We have given
A triangle with angle 39 degree and hypotenuse = x.
Adjacent side = 7 .
Cos(theta) = .
Plug the values
Theta = 39 degree.
Cos(39) = .
x = .
x = 9.09
Nearest tenth is 9.09
Therefore, x = 9

Answer:
The distance between two points ( -1,1) and (2,-4) is:
or d = 5.8 units.
Step-by-step explanation:
Given the points
- (-1, 1)
- (2, -4)
Finding the distance between (-1, 1) and (2, -4) using the formula
substitute (x₁, y₁) = (-1, 1) and (x₂, y₂) = (2, -4)
units
or
units
Therefore, the distance between two points ( -1,1) and (2,-4) is:
or d = 5.8 units.
