Draw 20 squares. Place the squares in a grid pattern. You can have 5 rows, and you'll have 4 squares in each row. This gives 5*4 = 20 squares total. This is one way to represent 20÷5 = 4.
Answer:
the answer is D
Step-by-step explanation:
Think of the Pythagorean Theorem which states that a^2 + b^2 = c^2. The Pythagorean Identities used in trigonometry are the angle version which can be used to simplify expressions.

Step-by-step explanation:
In an isosceles triangle, both legs are always congruent. The length of one leg is given, and the other leg has to be the same. The perimeter of this triangle can be written as:
With this equation, all you need to do is solve for x.
Answer:
x=25°, y=10°
Step-by-step explanation:
∠A+∠B=180°
8y+10y=180°
18y=180°
y=10°
∠B+∠C=180°
10y+4x-20°=180°
10*10°+4x=180°+20° (y=10°)
100°+4x=200°
4x=200°-100°
4x=100°
x=25°
