Bonsoir à tous, j'ai besoin d'aide urgemment en maths si possible et merci d'avance. L'exercice est photographié ci-dessus

Answers

Answer 1

Answer: m<SAB = 180 - 58,5 = 121,5

180 - 121,5 - 34,1 = 23,4

(sin 121,5)/SB = (sin 23.4)/18,7

SB = (sin 121,5 * 18,7)/(sin 23,4)

SB = 40,15

sin B = h/SB

h = (SB) * sin B

h = 40,15 * sin 35.1

h = 23,1

What is the value of x? º A triangle with base on an extended line. Two angle measures are given. Top interior angle is twenty-eight degrees. Lower left exterior angle is seventy-one degrees. Lower right interior angle is labeled x degrees.

Answers

All interior angles of a triangle must have a sum of 180°.
Interior angle of a triangle and its corresponding exterior angle must have a sum of 180° when its line is extended.

Top interior angle is 28°
Lower left exterior angle is 71°
Lower right interior angle is x°

Get the left interior angle.
Exterior angle + Interior angle = 180°
71° + Interior angle = 180°
Interior Angle = 180° - 71°
Interior Angle = 109°

Top Interior angle + Left Interior Angle + Right Interior angle = 180°
28° + 109° + x° = 180°
x = 180° - 28° - 109°
x = 180° - 137°
x = 43°

The lower right interior angle is 43°

The table shows the number if votes for the new school mascot. What percent of the students chose a mascot other than Tigers?Mascot|| Number of students

Polar bears|| 6
tigers|| 14
vikings|| 19
eagles|| 11

Answers

The total votes are 50. If you are finding out the percentage of students that did not choose the Tigers, you would subtract the Tigers votes from the total. 50-14 =36. 36/50 would equal .72, turn that into a percent and you have 72% of students not voting for Tigers.
