Answer:
t12= -8
Step-by-step explanation:
t3
a+2d=10 (1)
t10
a+9d=-4. (2)
From (1)
a=10-2d. (3)
Sub into (3) into equ (2)
a+9d=-4
10-2d+9d=-4
10+7d=-4
7d=-4-10
7d=-14
Divide both sides by 7
d=-14/7
d= -2
10=a+2d
10=a+2(-2)
10=a-4
10+4=a
14=a
a=14
t12=a+11d
= 14+11(-2)
=14-22
= -8
t12= -8
Answer:
$24.15
Step-by-step explanation:
What you do is you take 15% and make it into a decimal which is .15.
Then you times it by $21. 21*.15=3.15.
You then take the $3.15 and add it to $21 to get
$24.15 as your answer.
Answer:
Step-by-step explanation:
<u>Finding the missing angle</u> :
- 22° + ∠R + 72° = 180°
- ∠R = 180° - 94°
- ∠R = 86°
<u>Applying the Law of Sines</u> :
<u>Substituting the known values</u> :
- sin 22° / P = sin 86° / 18
- P = sin 22° × 18 / sin 86°
- P = 0.374606593 × 18 / 0.99756405
- P = 6.76 cm
This is what I got:
sin 54 ° = 0.80901699
I’m not sure what the [?] is cause I see no number beneath it either but I hope this somehow helps
