Ineed the angles to an isosceles triangle one at x degrees and on at 28 degrees

Either x = 124 deg or x = 76 deg depending on which angle measure appears twice.

Step-by-step explanation:

An isosceles triangle has at least two congruent angles. You don;t say which angles are congruent, and there is no figure, so there are two possibilities.

1) Two angles measure 28 deg, and one angle measure x degrees.

2) Two angles measure x degrees, and one angle measures 28 deg.

Possibility 1)

28 + 28 + x = 180

x + 56 = 180

x = 124

Possibility 2)

x + x + 28 = 180

2x + 28 = 180

2x = 152

x = 76

d. bc = 12 and ef = 16

step-by-step explanation:

we are given that δabc : δdef such that .

also, it is given that

so, from the options, we need that .

a.

b.

c.  

d.

as, we can see that only option d gives the same ratio as i.e. .

hence, the possible lengths are bc = 12 and ef = 16.
