(-2)^4 = (-2) (-2) (-2) (-2) = 16
so n = 16
Answer:
70 yd.
Step-by-step explanation:
The three streets at the intersection form a right triangle.
For a right triangle, the length of the longest side (called hypothenuse) is given by Pythagorean's theorem:

where
x is the length of the 1st side
y is the length of the 2nd side
h is the length of the hypothenuse
Here we want to find the hypothenuse.
We have:
x = 42 yd (length of the 1st side)
y = 56 yd (length of the 2nd side)
Substituting, we find h:

When substituting, you want to take the y value from one equation and plug it into the y variable in the other equation to find the x value. When you find the c value, you plug the number into one of the equations to get your y value.
406 divided by 140 makes 2.9 multiply that 100 and you arrive at 290%. Hope this helps!
A cyclic quadrilateral is a quadrilateral inscribed in a circle
The measure of angle A is 106
<h3>How to determine the measure of angle A</h3>
From the question, we have:
<C= 74
Opposite angles of a cyclic quadrilateral add up to 180.
So, we have:
<A + <C = 180
This gives
<A + 74 =180
Subtract 74 from both sides
<A =106
Hence, the measure of angle A is 106
