Answer:
Two triangles are said to be similar if their corresponding angles are congruent and the corresponding sides are in proportion . In other words, similar triangles are the same shape, but not necessarily the same size. The triangles are congruent if, in addition to this, their corresponding sides are of equal length.
Answer:
20 square feet
Step-by-step explanation:
Area of a triangle is half the area of a rectangle. (when they have the same length and width!)
To get the area it would be 10 *2 = 20
Answer:
x = 182.53
Step-by-step explanation:
Use trigonometric ratios to find the whole side length (a) adjacent to 20° and the side length (b) adjacent to 57° respectively. Then find the difference. That would give you the value of x. That is: a - b = x
Let's solve.
✍️Finding the whole side length adjacent to 20°:
Opp = 87
Adjacent length = ? = a

Thus,

Plug in the values

Multiply both sides by a


Divide both sides by tan(20)



Finding the side length adjacent to 57°:
Opp = 87
Adjacent length = ? = b

Thus,

Plug in the values

Multiply both sides by b


Divide both sides by tan(57)



Therefore:
x = a - b
x = 239.03 - 56.50
x = 182.53
