Hi, can someone help me with this question?

hi

Step-by-step explanation:

firstly we must divide the shape like this

and the area of first rectangular is 27 m²( 9m × 3m)

then second rectangular's area is 48m²( 12m × 4m and we found 4m from 9-5)

the third rectangular's area is 10 m² ( we found it from 9-4)

Total is 27+48+10=85 m²

hope it helps

have a nice day

(1,4) is on graph of f(x)

f(1) = 4

so 1/4 f(x)

1/4 f(1)

1/4. ×4

1

so point for function 1/4. f(x) is (1,1)

according to the triangle sum theorem, all the angles in a triangle must add up to 180 degrees. if we know one angle is already 90, we do 180-90=90. the other 2 angles must add up to 90, exactly.
