Using angle measures in triangles

Mathematics
1 answer:
julsineya [31]4 years ago

Answer:x = 45

Step-by-step explanation:

The sum of the angles in a triangle is 180 degrees. The angles in the given triangle are

Angle p is 25

angle r is 20

angle q is 3x

Therefore,

Angle p + angle r + angle q = 180

25 + 20 + 3x = 180

45 + 3x = 180

Subtracting 45 from the left hand side and the right hand side of the equation, it becomes

45 - 45 + 3x = 180 - 45

3x = 135

Dividing the left hand side and the right hand side of the equation by 3, it becomes

3x/3 = 135/3

x = 45

Answer:

Quotient: x+7

Remainder: -2

Step-by-step explanation:

Divide the terms (x² ÷ x =x)↓

(x² + 11x + 26) ÷ (x + 4) =x

Subtract x² + 4x (You have to the sign if each term)

(x² + 11x + 26) ÷ (x + 4) =x

-x² - 4x

-------------------

      7x + 26      

Divide the terms (7x ÷ x = 7)

x² + 11x + 26) ÷ (x + 4) =x + 7

Multiply the quotient by the dividend (x + 4) × 7 = 7x+28

(x² + 11x + 26) ÷ (x + 4) =x

-x² - 4x

-------------------

      7x + 26      

      7x + 28

------------------

           = -2 Remainder
