Answer:

a. 18 b. 119°, 118°

Step-by-step explanation:

a. Given angles are vertical, so they are equal.

6a+11 = 2a+83

6a-2a = 83-11

4a = 72

a = 72/4

a = 18

b. Substituting the value of a in the given angles,

6a+11 = 6*18+11 = 108+11 = 119°

2a+83 = 2*18+83 = 36+83 = 118°

In this diagram, bac~edf. if the area of bac= 6 in.², what is the area of edf? PLZ HELP PLZ PLZ PLZ

NemiM [27]

Answer:

2.7 in²

Step-by-step explanation:

Area of ∆BAC : ∆Area of EDF = BC² : EF² (based on the area of similar triangles theorem)

Thus:

$6 in^2 : x in^2 = (3 in)^2 : (2 in)^2$

$\frac{6}{x} = \frac{3^2}{2^2}$

$\frac{6}{x} = 2.25$

$\frac{6}{x}*x = 2.25*x$

$6 = 2.25x$

$\frac{6}{2.25} = \frac{2.25x}{2.25}$

$2.67 = x$

Area of ∆EDF = 2.7 in²
