Cos ( ∠C ) = 5/13 = 0.38462
m ∠C = cos^(-1) 0.38642 = 67.4°
m ∠A = 90° - 67.4° = 22.6°
m ∠C - m ∠A = 67.4° - 22.6° = 44.8°

Shape A and Shape B are each made from 5 identical squares.
Morgarella [4.7K]

Answer:

Perimeter of shape B = 50 cm

Step-by-step explanation:

Perimeter of shape A = 60 cm

Let the length of each square = x cm

Total length of free boundaries of shape A = 12x

Therefore, 12x = 60

x = 5 cm

Now length surfaces of shape B = 10x

Perimeter of shape B = 10x

                                    = 10(5)

                                    = 50 cm

Which equation is quadratic in form?
densk [106]

A quadratic equation is written in the form  ax^{2} + bx + c = 0

Looking at the second, third, and fourth options, we see that the highest powers are greater than two, which automatically disqualifies them from being quadratics (since the highest power in a quadratic is 2).

This makes the first option the correct choice since the expansion of the equation gives 2x^{2} + 28x + 61
