Sin60 =b/10
<span>√3/2 = b/10
</span>b = <span>√3 / 2 (10)
</span>b = 5<span>√3
</span>
d^2 = 10^2 - (5√3)^2
d^2 = 100 - 75
d^2 = 25
d = 5
sin30 = b/a
1/2 = 5√3 / a
a = 5√3 (2)
a = 10√3
c^2 = (10√3)^2 - (5√3)^2
c^2 = 300 - 75
c^2 = 225
c = 15
so
a =10√3, b = 5√3, c = 15,d = 5
answer is
D. last choice
She will be 56 after 14 years from now
Step-by-step explanation:
1 Find common denominator (lower numbers)
2 add numerators(top numbers)
3 put the numerator over the denominator
ex 3/4+2/8
3x2=6,4x2=8
3/4=6/8
6/8+2/8=8/8 or 1
Answer:
4
Step-by-step explanation:
ARC = , b = 7, a = 1
24/6 = 4
