Jack is a civil engineer and uses angle relationships to design public structures such as buildings, bridges, and streets. He designs walking paths in a park as shown below.

Rectangle A B C D has diagonals B D and A C that intersect at the center of the rectangle at point M. Angle M A D is 30 degrees and angle M D A is 60 degrees.

What is the measure of angle BMA where the diagonals meet?

°

The measure of angle BMA is 90 degrees

Step-by-step explanation:

The picture of the question in the attached figure

step 1

Find the measure of angle AMD

we know that

The sum of the interior angles in any triangle must be equal to 180 degrees

In the triangle MAD

substitute the given values

step 2

Find the measure of angle BMA

we know that

---> by supplementary angles (form a linear pair)

substitute the given value

i think it would be c

mark brainliest if im right

step-by-step explanation:

a≈380.13mi² would be your answer if the radius was 11 miles
