Mathematics

Answer:

C. x = 8 , y = 40

Step-by-step explanation:

since this is an Isosceles triangle 5x = 40° and x = 8

The sum of interior angles in a triangle is equal to 180°

40° + 5x + 2y + 20 = 180° add like terms

5x + 2y = 120

40 + 2y = 120 ➡ 2y = 80 and y = 40

Step-by-step explanation:

AB =AC

Therefore,∆ABC is an isosceles triangle.

angle B= angle C

5x°= 40°

x°= 8°

Now, sum of the interior angles of the triangle= 180°

angle A+angle B+angle C=180

2y+20°+5x+40°=180°

2y+20°+40°+40°=180°

2y+100°=180°

2y=80°

y=40°

option C ,x = 8 ; y= 40°

Two thirds of a number reduced by 11 is equal to 4 more than the number. Find the number. n= Answer
Ira Lisetskai [31]

Answer:

-45

Step-by-step explanation:

2/3x - 11 = x + 4

  • I created an inequality representing the above statement first. This makes things look less complicated than what the question is asking.

2/3x = x + 15

  • solve for x. I started by adding 11 to both sides.

-1/3x = 15

  • multiply both sides by -3

x = -45
