Answer:
4.891
its side b (opposite side of the 50 degree angle)
Step-by-step explanation:
side c = 6
angle A is 20 side a (opposite side) = 2.184
angle B is 50 side b (opposite side) = 4.891
angle C is 110 side c (opposite side) = 6
1.
get third angle
50 + 20 = 70
180 - 70 = 110
third angle C is 110
2.
get side a
sin A/a = sin C/c
a/c = sinA/sinC
a = c * sinA/sinC
a = 6 * (sin20/sin110)
get sin in degrees
a = 6 * (.342/.9397)
a = 2.184
Answer:
114, and 115
Step-by-step explanation:
114+115 = 229
First 1/5 is equivalent to 20% so to get 20% of both of them multiply by .2. so 400×.2=80 and 90×.2=18
Answer:
?= 3
Step-by-step explanation:
let x = ?
18-2x=4x
6x=18x
x=3
