I tried solving it and I didn’t get the right answer can someone explain to me

X=29°

Step-by-step explanation:

Since triangles ABC and DEC are congruent, Angle A = Angle D = 74°

Sum of all angles in a triangle is 180°

So, Angle A + Angle B + Angle C =180°

74°+2X+48°=180°

2X=180°-122°

2X=58°

X=29°

Explanation:

When it comes to congruence statements like this, the order of the letters is important. This is so we pair up the letters properly.

ABC has A first, B second, C third

DEC has D first, E second, C third

So we have these pairings

Which leads to

Due to the fact that congruent triangles have congruent corresponding parts.

Since B = E and B = 2x, we can say that E = 2x by either substitution or the transitive property. Both effectively say the same thing.

Now focus on triangle CDE

The three angles we have are

Those three angles add to 180. This is true for any triangle.

C+D+E = 180

48+74+2x = 180

122+2x = 180

2x = 180-122

2x = 58

2x = 58/2

x = 29

Side note: since x = 29, this means angle B = 2x = 2*29 = 58, and this is the measure of angle E as well.

We can check the answer by doing C+D+E = 48+74+58 = 180. So we have confirmed the answer.

46 dollars is the answer.

step-by-step explanation:

6*6 = 36,         36+10=46

the smallest possible measurement of the width is 14 feet

step-by-step explanation:

let's assume length of parallelogram is 'l'

width of parallelogram is 'w'

the perimeter of a parallelogram must be no less than 40 feet

so, we get

we are given

length of parallelogram is 6 feet

so,

l=6

we can plug it

now, we can solve for w

subtract both sides by 12

divide both sides by 2

and we get

so,

the smallest possible measurement of the width is 14 feet
