Answer:

C. The triangles are not similar

Step-by-step explanation:

For two triangles to be considered similar, the 3 angles of one triangle must be equal or congruent to the corresponding 3 angles of the others.

The only angle in ∆BCG that is equal to the corresponding angles in ∆EFG is <BGC. The remaining 2 angles in ∆BCG are not congruent to the corresponding 2 angles in ∆EFG.

Therefore, we can conclude that both triangles are not similar.

iragen [17]

Answer:

b

Step-by-step explanation:

Minimum sample size for estimating the population proportion of pine trees over 90 years old in a forest near where you live with <em>margin of error</em> no more than 2% can be calculated using the equation:

n≥ p×(1-p) × $(\frac{z}{ME} )^2$ where

n is the sample size

p is the proportion of pine trees over 90 years old in a forest near where you live

z is the corresponding z-score for the confidence level

ME is the margin of error in the estimation (2% or 0.02)

If 8x+6=4x+38
8x-4x=38-6
4x=32
x=32/4=8

Angle of A is equal to angle of B (mirrored)

Then angle of B is 4x+38 = 4*8+38 = 32+38=70
