Answer:
6 inches
Step-by-step explanation:
IF there are 6 beads in total, that are 1 inch each, 6 x 1 would be 6, therefore its 6 inches
All angles in a triangle add to 180 so
B = 180 - 90 - A
B = 90 - 20.8
B = 69.2
Can find b with tangent of A
tangent is opposite over adjacent.
opposite to A = 20.8 is 11.2 and adjacent is b
tan(20.8) = 11.2 / b
b = 11.2 / tan (20.8)
b = 29.5
c can be found with sine of A
sin(20.8) = 11.2 / c
c = 11.2 / sin(20.8)
c = 31.5
B = 69.2°, b = 29.5, c = 31.5
Answer:
im not sure but i think its 151200
Step-by-step explanation:
12000 + %5 = 12600 x 12 = 151200 i could be completely wrong tho
5/4+4m/5 =61/20
multiply each side by 20 to clear the fractions
20 *( 5/4+4m/5 ) = 61/20 * 20
distribute
25 + 16m = 61
subtract 25 from each side
16m = 36
m = 36/16
m = 9/4
m = 2 1/4
Check:
5/4+4m/5 =61/20
5/4 + 4/5 * 9/4 = 61/20
5/4 + 36/20 = 61/20
get a common denominator
25/20 +36/20 = 61/20
61/20=61/20
