Polygon A B C D E F has 6 sides. Exterior angle A is 62 degrees, exterior angle B is 44 degrees, exterior angle C is 70 degrees,
nevsk [136]

The measure of angle AFE would be 99 degrees.

Step-by-step explanation:

Given that,

Exterior angle A = 62 degrees

Exterior angle B = 44 degrees

Exterior angle C = 70 degrees

Exterior angle D = 60 degrees

Exterior angle E = 43 degrees

Angle AFE = ?

However, for that, we have to find the exterior angle of F.

We know that the sum of exterior angles of polygon is 360 degrees.

Exterior angle( A + B + C + D + E + F) = 360 degrees

Exterior angle F = 360 - Exterior angle( A + B + C + D + E )

Exterior angle F = 360 -  (62 +44 + 70 + 60 + 43 )

Exterior angle F = 360 -  279

Exterior angle F = 81

The, sum of interior and exterior angle is 180 degrees. Therefore, the angle AFE would be 180 - 81 = 99 degrees.

Keywords: polygon, exterior angle

Show that the triangle below is not a right-angled triangle.
Paha777 [63]

Step-by-step explanation:

A right triangle is a triangle in which one of the angles is a 90∘ angle.

(5x - 8)  + (2x - 5)  + (2x  + 3) = 180 \\ 9x - 10 = 180 \\ 9x = 190 \\ x =  \frac{190}{9}  \\ x = 21.11

(5x - 8) =97.56  \\ (2x - 5)  =37.22  \\ (2x + 3) =45.22  \\

Since None of the angels is 90° , so the triangle is not a right triangle.

Find the value of m < 7 .
lesya [120]

Answer:

B

Step-by-step explanation:

the exterior angle of a triangle is equal to the sum of the 2 opposite interior angles.

∠ FES is an exterior angle of the triangle , then

57° + ∠ F = 142° ( subtract 57° from both sides )

∠ F = 85°
