Answer:
B = 75°
Step-by-step explanation:
Using the Sine rule:
a / sin A = b / sin B = c / Sin C
a / sin A = b / sin B
20 / sin 48 = 26 / sin B
Cross multiply :
Sin B * 20 = sin 48 * 26
Sin B = (sin 48 * 26) / 20
Sin B = 0.9660882
B = sin^-1(0.9660882)
B = 75.036
B = 75°
To find the area of the figure you first have to split them up. To find the area for the triangle do 30 x 34 x 16= 16320
Then you find the area of the other shape:
30 x 30 x 16 x 40 = 576000
Then you add them together to get the answer:
576000+16320=592320
So, the answer is 592,320

In 2000 Emily was 9 years old.
Given that in the year 2015 Emily was three times as old as Kaitlin while by the year 2021 Kaitlin will be half as old as Emily will be, to determine how old was Emily on the year 2000 the following calculation must be performed:
- 2015 = E = 3K
- 2021 = E = 2K
- 24 /// 8 --- 30 /// 14
- 18 /// 6 --- 24 /// 12
- 18/6 = 3
- 24/12 = 2
- 2015 = Emily was 24 years old
- 24 - (2015 - 2000) = X
- 24 - 15 = X
- 9 = X
Therefore, in 2000 Emily was 9 years old.
