Answer:
A = (x^2)/2
Step-by-step explanation:
Represent the length of one side of the square by s. Then, according to the Pythagorean Theorem,
x^2 = s^2 + s^2, or x^2 = 2s^2, or (solving for s^2), s^2 = (x^2)/2
This last result is the area of the square in terms of x: A = (x^2)/2
Answer:
49.2°
Step-by-step explanation:
To solve for x you'll need to find the cosine of x°.
To find the cosine you will need to divide the adjacent side to it by the hypotenuse.
cos x°= 
Using a calculator to solve you'll get that x ≈ 49.2°
4 x+9=13 X=4 subtract 9 from the 9 and 13 and 13-9 =4 so x=4
The Area of the trapezoid is 88 not 91
Answer:
A = 16 13unit^2 + 9unit^2 = 5 √10 = 15.8 = 16
Step-by-step explanation:
For Pythagoras we square route
= x^2 = 13^13 + (one of the closer squares for x elimination)
x= 169 + 81 169 + 100 169 + 49 169+64 169 + 121
x = 250 or 269 or 218 or 233 or 290
x= 5√10 or 15.8 or √269 269 or √218 2.8 or √233 or 2.33 ( or √290 = ( √48+2) or 2.9
