Answer:
Below.
Step-by-step explanation:
One example is a square.
Another is a rectangle.
Both of these contain 4 right angles.
Squares & Rectangles
Both of these quadrilaterals have 90 degree angles (right angles), no acute angles.
Answer: X = 20
7x - 99 = 2x + 1 --Take 2x from both sides
-2x -2x
5x - 99 = 1 -- add 99 to both
+99 +99
5x = 100 --Divide by 5
÷5 ÷5
x = 20
x = 2/5
5x=2
Divide each side by 5
5x/5 = 2/5
As,
=0.301029+0.845098+1.13943
=2.26007
=2.260(approximate)
Answer: y = 5/3x - 4
