Z=56°
explanation: since the one angle is 90°, you need to take 68 away from 90, you get 22. then since the line between angle 78° and y, would add up to 120°, you must take 78° away from 120°, giving you 42 for angle y. now for 3-sided triangles, their 3 angles add up to 120°, so add 42 and 22, you get 64, and finally take 64 away from 120 and you get angle z, which is 56°

Answer:

z = 86

Explanation:

90 - 68 = 12
180 - 78 = 102
102 + 12 = 114
180 - 114 = 86

The relationship between the length of one side of the Square, eggs, and the perimeter of the Square, why, can be represented in
oee [108]

Answer:

The points with coordinates (x, y) that are on the line of the equation of the line relationship between the side of a square, x and the perimeter, y include;

(1, 4), (2, 8), (3, 12) ....(n, 4·n).

Where n is a positive number.

Step-by-step explanation:

The formula to determine the length of the perimeter of a square is,

Length of the perimeter of a square = Length of a side of the square multiplied by 4.

That is Perimeter of square = Side of square × 4

The relationship between the length of one side of a square and the perimeter of the square can be represented by the equation

y = 4×d which is a straight line with a slope of 4 passing through the origin

Points o the line include

(1, 4), (2, 8), (3, 12), etc.

The x and y coordinates take the form

(x, 4·x)

Write a proportion for 56% of a number is 244
Misha Larkins [42]
\frac{56}{100} =  \frac{244}{x} So, You cross multiply and get 56x=244(100). Simplify and you get 56x=24400. Divide each side by 56 and you get 435.71. 56% of about 435.71 is 244.
