Tangent 45 = height / 3
height = 3 * tan (45)
height = 3 * 1
height = 3

Trapezoid area = ((sum of the bases) ÷ 2) • height

Trapezoid area = (9 + 15) /2 * height

Trapezoid area = 12 * 3

Trapezoid area = 36

Ashley, Milan, and Carlos sent a total of 131 text messages over their cell phones during the weekend. Carlos sent 7 times as ma

nordsb [41]

Answer:

Ashley= 15

Milan= 11

Carlos= 105

Step-by-step explanation:

Let, A, M and C denotes Ashley, Milan and Carlos respectively.

A+M+C= 131 (according to the question)

Here,

C= 7A

A= M+ 4

So, M= A - 4

Now,

A+M+C = 131

or, A+ A-4+ 7A = 131 (putting the values)

or, 9A - 4 = 131 (adding like terms i.e. A + A + 7A)

or, 9A = 131 + 4

or, 9A = 135

or, A = 135 / 9

So, A = 15

C= 7A = 7×15= 105

M= A-4 = 15 - 4 = 11

What is the measure of angle C? A. 110 B. 72 C. 108 D. 70

Eduardwww [97]

Answer:

68º

Step-by-step explanation:

every quadrilateral has a total of 360º when adding all of the angles.

so since angle D and A are the same you add them along with angle B

110+110+72=292

then you subtract 360-292= 68º

Hope this helped!! Make sure to mark as brainliest :)
