Answer:

Area of first shape is 288ft^{2}, area of second shape is 45m^{2}, area of third shape is 34in^{2}.

Area of first shape

A=bh

A=18*16

A=288

Second shape

A=bh

A=9*5

A=45

Third shape

A= 1/2 h(b1+b2)

A=1/24(12+5)

A=1/2*4(12+5)

A=1/2*4(17)

Answer:

m<E = 77^{o}

Step-by-step explanation:

From the diagram, ΔACE and ΔBDE are similar. So that comparing its angles, we have;

(8x + 4) = (9x - 5)

8x + 4 = 9x - 5

5 + 4 = 9x - 8x

x = 9

Thus,

(8x + 4) = 8(9) + 4 = 76

(9x - 5) = 9(9) - 5 = 76

3x = 3(9) = 27

From ΔACE,

3x + (8x + 4) + m<E = 180 (sum of angles in a triangle)

27 + 76 + m<E = 180

m<E = 180 - 103

m<E = 77^{o}
