Find the value of x in the triangle, 60°, 60°, 5x​

Answers

The value of x in the expression for the angle of the triangle is 12.

What is the value of x in the triangle?

The figure in the image is a triangle.

From the image:

Angle 1 = 5x

Angle 2 = 60 degrees

Angle 3 = 60 degrees

Note that, the sum of the interior angle of a triangle equals 180 degrees.

To determine the value of x, add the 3 angles and equate to 180 degrees.

Hence:

5x + 60 + 60 = 180

Collect and add like terms:

5x + 120 = 180

Subtract 120 from both sides:
5x + 120 - 120 = 180 - 120

5x = 180 - 120

5x = 60

x = 60/5

x = 12

Therefore, x has a value of 12.

Triangles have well 3 angles, and they all add up to 180. So 180-60-60= 60. This means that 5x=60. So you divide by 5 on each side and get x=12.

There are 27 red or blue marbles in the bag. The number of red marbles is 5 less than 3 times of the blue marbles. How many red marbles are in the bag? How many blue marbles are in the bag?

Answers

Let

x--------> The number of red marbles

y--------> The number of blue marbles


we know that

x+y=27\n x=27-y

equation 1


x=3y-5

equation 2


equate equation 1 and equation 2

27-y=3y-5\n 3y+y=27+5\n 4y=32\n y=8

x=3*8-5\n x=19

therefore


the answer is

The number of red marbles is 19

The number of blue marbles is 8

27=3x-5+x
27+5=4x-5+5
4x=32
4x/4=32/4
x=8
There are 8 blue marbles and 19 red marbles.
