We multiply 38 by 45 to get 1710. This is already in simplest form, although we can convert it to scientific notation as 1.71*10^3 if you wish.
Answer:
Angle D is equal to 80.
Step-by-step explanation:
We know that the sides are congruent and that angle ACB is congruent to angle ECD by the vertical angles theorem.
Triangles' angles always add up to 180.
180 - 70 - 30 = 80
angle D is equal to 80.

Step-by-step explanation:
Rachel needs 1776 inches of board
<em><u>Solution:</u></em>
Given that, Rachel is making a planter box
Her box measures 345 inches long and 543 inches wide
Length = 345 inches
Width = 543 inches
<em><u>To find: Inches of board she needs</u></em>
So we need to find the perimeter of the board
The board is usually of rectangular shape
<em><u>Perimeter of rectangle is given as:</u></em>
Perimeter = 2(length + width)
Perimeter = 2(345 + 543)
Perimeter = 2(888)
Perimeter = 1776
Thus she needs 1776 inches of board
