2) 5x +x = 180 ;  6x = 180 ; x = 180/6 = 30

3) 90

4) x + 6x+8 + x+12 =  180 ;  8x + 20 = 180 ;  8x = 160/8= 30

5)  180 -110 = 70

6) m = 180- 119 = 61

7) 90

8) 11y - 36 = 63 ;  y = 99/11 = 9

(Q7) 180

(Q8) 2x+x = 3x = 90 ;  x = 90/3 = 30

(Q15) 157

(Q16) 5x + 4 + (x-2) + (3x+7) = 180

       9x +9 = 180 ;   x = 171 / 9 = 19

rusak2 [61]

Answer:

40 square inches.

Step-by-step explanation:

It is given that the new club sticker is in the shape of a triangle.

Height of triangle = 8 inches

Base of triangle = 10 inches

We need to find the area of sticker.

Area of triangle =\dfrac{1}{2}\times base \times height

Substitute base = 10 and height = 8 in the above formula.

Area of triangle =\dfrac{1}{2}\times 10\times 8

Area of triangle =\dfrac{80}{2}

Area of triangle =40

Therefore, the area of the club sticker is 40 square inches.
