Angle 6= (11x+8) and angle 7=(12x-4) what is the measure of angle 4

Answer is m∠4=40

Step-by-step explanation:

take note that m∠6 & m∠7 are vertical angles. Vertical angles are equal to each other, therefore m∠6 is equal to m∠7.

m∠6 = m∠7 (vertical angles)

11x + 8 = 12x – 4

12x - 11x = 8 + 4

x = 12

so

m∠6 = 11x + 8  

m∠6 = 11(12) + 8

m∠6 = 132 + 8

m∠6 = 140

m∠4 = 180 - m<6

m∠4 = 180 - 140

m∠4 = 40

Volume of pyramid B is 8 times or 12.5% bigger than pyramid A.

Volume of pyramid A = 1/3 × base area × height.

Volume of pyramid B = 3136in³

Therefore,

Ratio of volume of pyramid B to pyramid A:

So, Volume of pyramid A is 8 times bigger than volume of pyramid B.
