Answer:
2. one angle is 108, and other is 72
3. x is 12
Step-by-step explanation:
the ratio is 3:2.
3x + 2x = 180
5x = 180
x = 36
36 x 3 = 108
36x 2 = 72
so that is why the two angles re 108and 72.
for the last question, 37 plus 41 plus x = 90
37 plus 41 is 78
90 - 78 = 12
so that is why x is 12.
Answer:
1: 0.625, 2: 1.05, 3: 2 13/20
Step-by-step explanation:
Use a calculator to determine the exact value of the fractions, or do it by hand.
First, we should calculate the areas separately.
4x8=32
5.6 x 4 = 22.4/2 = 11.2
4.5x4=22 22/2=11
4x8=32
32+11+32+11.2
64+22.2=86.2
So 86.2 ft2
Hope this helped. ^^
Answer:
x=7.8
Step-by-step explanation:
take 49 degree as reference angle
using cos rule
cos 49=adjacent/hypotenuse
0.65=x/12
0.65*12=x
7.8=x
Answer:
C. 248 square meters
Step-by-step explanation:
2(10 x 6) + 2(10 x 4) + 2(6 x 4)
