Answer:

B

Step-by-step explanation:

f(7)=\sqrt{7^2+8*7}=\sqrt{49+56}=\sqrt{105} \approx 10.247\\f(8)=\sqrt{8^2+8*8}=\sqrt{128}=8\sqrt{2} \approx 11.314\\f(8)-f(7)=11.314-10.247=1.067 \approx 1.07

What is the measure of angle B in the triangle?
sladkih [1.3K]
40 + 2x - 30 + x + 20 = 180
3x + 30 = 180
3x = 150
  x = 50

m<B = 2x - 30
m<B = 2(50) - 30
m<B = 100 - 30
m<B = 70
