Answer:
Width = 5 inches
Length = 9 inches
Step-by-step explanation:
The paper;
Length = (x + 4) inches
Width = x inches
The area is close as possible to 50 square inches.
Since this paper is rectangular in shape; the area of a rectangle is given by:
Area = Length × Width
∴ (x + 4) * x = 50 square inches
x² + 4x = 50
Let the area be equal to 45 square inches;
Applying the quadratic formula, x = 5 or -9
But since we are dealing with length measurements, the value of x = 5 inches.
So the width = 5 inches and;
length = 5 + 4 = 9 inches.
Solve y: 6.3 = 0.9y
6.3/0.9 = 0.9y/09
y = 7
Solve x: x + 7.72 = 19
x + 7.72-7.72 = 19 - 7.72
x = 11.28
What is y? 7 What is x? 11.28
The sum of all the angles in a triangle is 180°.
There is a right angle -> a 90° angle on the hypotenuse of the largest triangle (the largest being the one that contains both smaller triangles)
To solve this problem, you don't really need to solve y.
Next to the 48° angle, you have two of the same angles, both x variables.
The sum of these three angles has to be 180°

Now that we have x, we can calculate the value of z.
We add the value of x and the 90° angle, we later subtract it from 180°
Calculating the value of z:

If you really want to know the value of y, you just add up the 90° angle and the 48°, then subtract that from 180°
