Answer:
x = 88
Step-by-step explanation:
All angles in a triangle equal 180 degrees. So our equation will be:
x + 48 + (x - 44) = 180
x + 48 + x - 44 = 180
2x + 48 - 44 = 180
2x + 4 = 180
2x = 176
x = 88
Hope this helps!
Circle formula
(x-h)^2+(y-k)^2=r^2 where (h,k) is the center
and r=radius
to find the radius
we are given one of the points and the center
distnace from them is the radius
distance formula
D=

points (-3,2) and (1,5)
D=

D=

D=

D=

D=5
center is -3,2
r=5
input
(x-(-3))^2+(y-2)^2=5^2
(x+3)^2+(y-2)^2=25 is equation
radius =5
input -7 for x and solve for y
(-7+3)^2+(y-2)^2=25
(-4)^2+(y-2)^2=25
16+(y-2)^2=25
minus 16
(y-2)^2=9
sqqrt
y-2=+/-3
add 2
y=2+/-3
y=5 or -1
the point (-7,5) and (7,-1) lie on this circle
radius=5 units
the points (-7,5) and (-7,1) lie on this circle
First, multiply each side by 5
6(x+1) = 25x-15
distribute the 6
6x+6=25x-15
put the x's on the same side and the other numbers on the opposite side
21=19x
Divide by 19 to isolate the x
21/19=x
Answer:
Sine, cosine and tangent
Step-by-step explanation:
Given a right triangle you can find the sine (or cosine, or tangent) of either of the non- 90° angles.
The Length of third side of the triangle is 4x +5
What is the Triangle?
A triangle is a three-sided polygon that consists of three edges and three vertices. The most important property of a triangle is that the sum of the internal angles of a triangle is equal to 180 degrees. This property is called angle sum property of triangle.
How to determine the length of the third side of the Triangle?
The given parameters are:
Length of the first side = 3x+2
Length of the second side =7x-4
Perimeter of the triangle =14x+3
Now, The perimeter is the sum of the sides of lengths
So, we have
Perimeter = sum of the sides of lengths
According to the question:
14x+3 =3x+2 +7x -4 + third side
Evaluate the like terms
14x-10x = -2 -3
third side = 4x + 5
Hence, The length of the third side of the triangle is 4x+5
