Answer:
20° and 70°
Step-by-step explanation:
Complementary angles sum up to 90°.
The angle = x
Its complement = x + 50
x + x + 50 = 90
2x = 40
x° = 20°
20+50=70
The different colours that has been used is red, yellow and blue and the number of central squares is = 73 boxes
<h3>The Mondrian's work</h3>
The First division that was divided into 9 equal parts has = 1 coloured red.
The second division is 8 remaining
uncoloured squares into 9 equal squares = 8×9= 72boxes
The number of boxes that was coloured yellow =8 boxes
The remaining uncolored boxes which is = 72 - 8 = 64 boxes
The third division is the division of each remaining uncolored boxes into 9. That is 64 × 9 = 576
The number of boxes that was coloured blue = 64 boxes
Therefore the number of central squares that has been coloured = 1 + 8 + 64
= 73 boxes

Answer:
The length of a side of the square is 6.3 units.
Step-by-step explanation:
When given vertices for a given shape, the length of the side is calculated using the formula:
√(x2 - x1)² + (y2 - y1)²
When given vertices (x1 , y1) and (x2 , y2)
Square ABCD has vertices A(-2,-3), B(4, -1), C(2,5), and D(-4,3). Find the length of a side
Side AB : A(-2,-3), B(4, -1)
√(x2 - x1)² + (y2 - y1)²
= √(4 -(-2))² + (-1 -(-3))²
= √ 6² + 2²
= √36 + 4
= √40
= 6.3245553203
≈ 6.3 units
B(4, -1), C(2,5),
√(x2 - x1)² + (y2 - y1)²
= √ (2- 4)² + (5- (-1))²
= √-2² + 6²
= √4 + 36
= √40
= 6.3245553203
≈ 6.3 units
C(2,5), D(-4,3).
√(x2 - x1)² + (y2 - y1)²
= √(-4 - 2)² + (3 - 5)²
= √-6² + -2²
= √36 + 4
= √40
= 6.3245553203
≈ 6.3 units
A(-2,-3), D(-4,3).
√(x2 - x1)² + (y2 - y1)²
= √(-4 -(-2))² + (3 - (-3))²
= √-2² + 6²
= √4 + 36
= √40
= 6.3245553203
≈ 6.3 units
About 151. That seems pretty close. If it is incorrect, sorry.
A) 86 x 4= Width (86x4)+8= Length
b) Width = 384, 384+8= 392. Length= 392
