all angles = 180 degrees total
add the ratios: 2 +4 +9 = 15
180/ 15 = 12
12*2 = 24
12*4 = 48
12*9 = 108
108 + 48 + 24 = 180
the three angles are: 24, 48 and 108
There is the answer hope it helps
5. they give dimes of 2 identical sides 25 & 5
25/5 = 5 so ABC is 5 times larger so 12 x 5 = 60
6. V= L x W x H/3 = 6.2 x 4.5 x 5.3 = 147.87/3 = 49.29 cubic cm
7 add both losses 3 and a half + 3 and a half = 728 and a half - 7 = 21 and a half
Answer:
1024 cm²
Step-by-step explanation:
There are 16 rods. A square has 4 equal sides, so each side must consist of 4 rods. The length of each rod is 8 cm, so the length of each of the square's sides is 32 cm. Therefore, the area of the square is:
A = s²
A = (32 cm)²
A = 1024 cm²
