Square + triangle = 16 square + circle = 15 triangle + circle = 17

Square + triangle = 16 square + circle = 15 triangle + circle = 17

Are you a system of linear equations with three variables?
The square is x, the triangle is y, and the circle is Z,
x+y=16,(1)
x+z=15,(2)
y+z=17,(3)
(1) Formula - (2),
y-z=1,(4),
(3) (4),
2y=18,
y=9,
z=8,
x=7,
The square is filled with 7,
Triangle filling 9
Round filling 8

In a triangle, angle 1 is 10% less than angle 2, and angle 2 is 10% less than angle 3

Angle 1 + angle 2 + angle 3 = 180
Angle 1 + angle 2 + angle 3 + 10 + 10 + 10 = 180
Angle 1 = 50
Angle 2 = 60
Angle 3 = 70

The degree ratio of the three angles of a triangle is 5:3:2. What are the degrees of each angle of the triangle
What triangle is there

The inner angle and time are 180 degrees
The ratio is 5:3:2
180×5÷(5+3+2)=90
180×3÷(5+3+2)=54
180×2÷(5+3+2)=36
So the three angles are 90 degrees, 54 degrees, 36 degrees

A triangle has an angle of 40 degrees, and the degree ratio of the other two angles is 5:2. What is the maximum angle of the triangle

The largest is (180-40) / (5 + 2) X5 = 140 △ 7x5 = 100 degree

(circle + triangle) * (circle + triangle) = 121 circle is equal to 7.5, how much is triangle equal to?

(circle + triangle) * (circle + triangle) = 121
∵ (circle + triangle) & ∵178; = 11 & ∵178;
‖ circle + triangle = 11
∵ circle equals 7.5
5 + triangle = 11
｜ triangle = 3.5

2 triangles = 3 squares, 3 squares = 4 circles; 1 triangle + 1 square + 2 circles = 400, ask triangle =?,

It can be seen from the question:
1 triangle = 3 / 2 squares
1 circle = 3 / 4 squares
1 triangle + 1 square + 2 circles = 3 / 2 squares + 1 square + 2 × 3 / 4 squares = 4 squares = 400
That is, 1 square = 100
1 triangle = 3 / 2 squares = 150

Triangle divided by five pointed star equals to square, square multiplied by five pointed star plus triangle equals to 150. How much is triangle equal to?

Triangle / five pointed star = box (1) Box * five pointed star + triangle = 150 (2) substitute the box of formula (1) = triangle / five pointed star into formula (2), (triangle / five pointed star) * five pointed star + triangle = 150, so triangle = 75

Known triangle divided by five pointed star equals square, square multiplied by five pointed star minus triangle equals 160, how much is triangle equal?

160/2=80

Triangle divided by five pointed star is equal to 13.3, triangle divided by five pointed star is equal to 13.5, then how many triangles and five pointed stars are there
Who knows,

3 = 0.5 * Pentagram
Pentagram = 6
Triangle = 13.5 * 6 = 81

Five pointed star plus triangle equals 16, five pointed star minus triangle equals 1, five pointed star is? Triangle is?
Ask to work out the number of five pointed stars and triangles

Let the five pointed star be x and the triangle be y
x+y=16
x-y=1
2x=17
x=17/2
y=15/2
The pentagram is 17 / 2 and the triangle is 15 / 2
