You need to draw the triangle DEF with a right angle at E. Angle D = 40 and DE = 100 m. Once you have marked up your triangle, you can use cosine to find DF.
2 miles = 10560 ft.
10560 ft + 3241 ft = 13801 ft.
Answer:
The area of triangle is 1263.6 mm².
This is an Equilateral triangle.
Step-by-step explanation:
Given that the area of triangle formula is A = 1/2×base×height. So you have to substitute the values into the formula :

Let base = 54mm,
Let height = 46.8mm,



This is the <u>E</u><u>q</u><u>u</u><u>i</u><u>l</u><u>a</u><u>t</u><u>e</u><u>r</u><u>a</u><u>l</u><u> </u><u>t</u><u>r</u><u>i</u><u>a</u><u>n</u><u>g</u><u>l</u><u>e</u> because all sides of the triangle are <u>e</u><u>q</u><u>u</u><u>a</u><u>l</u>.
