Answer:
the answer is
The surface area of Figure 1 is <u>10.2</u> square centimeters <u>Less</u> than the surface area of Figure 2.
Step-by-step explanation:
Figure 1
area of a square = s2
=9squared
=81 sq cm
area of triangle = 1/2 bh
=1/2 (9cm) (14cm)
=63 sq. cm
find surface area
SA = 81 sq. cm + 4(63 sq. cm)
SA = 81 sq. cm + 252 sq. cm
SA = 333 sq. cm
Figure 2 Calculation
area of rectangle = lw
a = (12cm) (8 cm)
a = 96 sq. cm
area of triangle = 1/2 bh
=1/2 (8 cm) (6.9 cm)
= 27.6 sq. cm
total surface are of figure 2
SA = 3 (96 sq.cm) + 2 (27.6 sq. cm)
SA = 288 sq. cm + 55.2 sq. cm
SA = 343.2 sq. cm
find the difference between figure 1 and figure 2
343.2 sq. cm - 333 sq. cm = 10.2 sq. cm
Answer: 62°
Step-by-step explanation:
Total angle in a triangle = 180°
40° + 78° + < N = 180°
118° + <N =180
<N = 180 -118
<N=62°
