What is the area of this composite shape?

51

Step-by-step explanation:

6 * 7 = 42

the side of the triangle can be found by subtracting 7 for 13, which is 6

so

6 * 3 = 18

since it's a triangle and the fomula is 1/2BH we're going to divide 18/2 to get 9

42 + 9 = 51

I took the test and this was the correct answer :^D

for any of you who need the translation here it is

step-by-step explanation:

find the angular size of the equatorial radius of the earth, if the horizontal parallax of the sun

answer: all the values are within because it has a pattern that repeats from -6 to 4.

good luck!
