The percentage of the questions she got wrong: 100%-55%=45%
Answer:
length is 3 units longer than the width.
Step-by-step explanation:
You can calculate the length and width of the rectangle by finding the difference between the x coordinates of the vertices and the y coordinates of the vertices, respectively
length = 4 - (-1) = 5
width = 5 - 3 = 2
So the length is 5 - 2 = 3 units longer than the width.

Step-by-step explanation:
If the expression 3x+10 is equal to 6 for some value of x, then what is the value of 3x+2 equal to for the same value of x ?
The measure of acute angle A to the nearest tenth of a degree is 51.2°
<h3>Measure of angles</h3>
From the given information, we are to determine the measure of the angle.
The angle we are to determine its measure is acute angle A
From the given information, we have that
sin A = 0.7793
Thus,
A = sin⁻¹(0.7793)
Using calculator
A = 51.1965°
A ≅ 51.2°
Hence, the measure of acute angle A to the nearest tenth of a degree is 51.2°
