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

Can someone please help me with this

Alex_Xolod [135]

Answer:

135°

Step-by-step explanation:

The reference angle appears to be about 45°, so a reasonable estimate of the angle size is 180° -45° = 135°.

You can do an eyeball comparison with the figure attached to see that the angle is about 135°

This is also the value I see when I place my protractor against the screen.

I NEED HELP ASAP! In a magic square, the sum of the numbers in each row, column, and diagonal is the same. Write and solve equat

Trava [24]

Answer:

$a=22,\\b=31,\\c=13$

Step-by-step explanation:

When choosing equations to write, make sure you choose a pair that allow you to isolate a variable and solve for it.

Sample solution:

$a+25+28=16+25+34,\\\\a+28=16+34,\\a+28=50,\\a=\boxed{22}$

$16+b+28=16+25+34,\\b+44=75,\\b=\boxed{31}$

$34+c+28=16+25+34,\\c+28=41,\\c=\boxed{13}$

△QRS is rotated about point P to △Q′R′S′ . Which statements are true about the pre-image and image?

yuradex [85]

Note that rotation will not affect the shape and size of an object.

Rotation with respect to a point preserves the corresponding sides and the corresponding angles of the original image.

Hence, the statements

The corresponding angle measurements in each triangle between the pre-image and the image are preserved and

The corresponding lengths, from the point of rotation, between the pre-image and the image are preserved

are true.
