Step-by-step explanation:
Cuz sides of square are same, we just find hypotenusa side of triangle (use Phytagoras Theorem) :
c² = a² + b²
c² = 2² + 4²
c² = 4 + 16
c² = 20
c = √20
Side of square is √20 units.
The area of square :
A = s²
= √20²
= √20 × √20
= <u>2</u><u>0</u><u> </u><u>units²</u>
So, the area of square is 20 units²

Since the total is 42 divide by two since they are the same length so it would be 21
Well, <T+<S will equal 11x +2
so the equation will be 5x+10 + 58 = 11x +2
5x + 68 = 11x +2
66 = 6x (subtract 2, subtract 5x)
x = 11 (division)
To check,
<T = 5 (11) +10
<T = 65
11(11)+2 = 123
<T+<S = 123
65+58 = 123
Answer:
Answer A
Step-by-step explanation:
We see that ABC is similar to DEF. Pay attention to the order of these letters. The order that they read (left-to-right) is the order that they are similar. For example, AB is similar to DE. Despite being different triangles, they are both the <em>first two </em>letters in the triangle. So, knowing this, we can conclude that answer choice A is correct.
