Step-by-step explanation:
5 ----> 45
1 ----> 45/5 = 9
8 ----> 9 ×8 = 72 p
The decimal computed shows that Tracy doesn't have enough for the construction.
<h3>How to calculate the length?</h3>
From the information given, Tracy has three pieces of wood that are each 8 meters long and one piece that is 7 meters long. Therefore, the addition of the lengths will be:
= (3 × 8) + 7
= 24 + 7.
= 31m
Since Tracy needs 31.5 meters of wood for a porch railing, it shows that she doesn't have enough.

Answer:
x = 7
Step-by-step explanation:
We can tell by looking at this triangle that this is a <u>45 45 90 triangle.</u>
In this situation, the hypotenuse is 
and the legs are both 
.So if we look at the hypotenuse, we can tell that x, or the leg of the triangle, is 7.
45 45 90 triangles: This is a special triangle in which the angles of the triangle are 45 45 and 90 degrees. This means that the hypotenuse will be and the legs of the triangle will be . You can usually use the Pythagorean theorem to solve the missing sides.
