Step-by-step explanation:
Square feet refer to the area of the triangle. Using the area formula (1/2bh), the area is calculated to be 4.375 square feet. If each square foot costs $.40 to make, then the correct process is to multiply 4.375 by .40, making the correct answer $1.75.
Answer:
x = √30
Step-by-step explanation:
For an equilateral triangle, the measure of the angle at each vertex is 60 degrees
Thus, the angle 60 faces the side measure x
Also, the given length is adjacent to the angle 60 measure
Mathematically, the trigonometric ratio that links the adjacent and the opposite is the tan
The tan is the ratio of the opposite to the adjacent
Thus;
Tan 60 = x/ root 10
x = root 10 * tan 60
x √(10 * √(3
x = √30
Answer:
AC = DB (Proved)
Step-by-step explanation:
Here, in the triangle ADE
AB = DC (Given)
Now, by EUCLID's LEMMA
If equals are added to equals, the sum are equal.
⇒ AB + BC = DC + BC
or, AC = DB
Hence Proved!
