Find the number of sides of a regular polygon with each interior angle equal to 157.5°. The regular polygon has sides.

yawa3891 [41]

The interior angle plus the exterior angle totals to 180 so you would take 180 and subtract 157.5 and get 22.5
next you would take 360 for the total of degrees that he external angles totals up to.
so 360 divided by 22.5 equals the number of sides you shape has and that would be 16 sides.

Answer: 10 units²

Step-by-step explanation:

We can divide the shape along the y-axis to get 2 separate triangles. If we find the area of each and add them up, we can get the total area of the figure.

We can get each triangle's area using the formula $A = \frac{1}{2}bh$

<h3>Left Triangle</h3>

base length - 4 units

height - 4 units

$A = \frac{1}{2}(4)(4)$

$A=\frac{1}{2}(16)$

$A =8\hspace{0.1cm}units^2$

<h3>Right Triangle</h3>

base length - 2 units

height - 2 units

$A = \frac{1}{2}(2)(2)$

$A=\frac{1}{2}(4)$

$A=2\hspace{0.1cm}units^2$

Total = 8 units² + 2 units² = 10 units²

Equation with angles can someone please answer helpppp

Answer:

$x = 18°\\\angle A = 73°$

Step-by-step explanation:

By interior angle property on one side of the transversal.

$\angle A+ \angle B = 180°\\6x - 35° + 3x + 53° = 180°\\9x + 18° = 180°\\9x = 180° - 18°\\9x = 162°\\x = \frac{162°}{9}\\ \huge \red {\boxed {x = 18°}} \\\therefore \angle A = 6x - 35°\\\therefore \angle A = 6\times 18°- 35°\\\therefore \angle A = 108°- 35°\\ \huge \purple {\boxed{\therefore \angle A = 73°}} \\$
