Answer:
14. m = 7/8
15 x =63
16. y= 21/2
Step-by-step explanation:
14. 7 16
---- = --------
m 2
using cross products
7 * 2 = 16 * m
14 = 16m
divide by 16
14/16 = m
simplifiy
7/8 =m
14. x 14
---- = --------
18 4
using cross products
4 * x = 18 * 14
4x = 252
divide by 4
4x/4 = 252/4
x = 63
15. 30 y
---- = --------
20 7
using cross products
30*7 = 20 y
210 = 20 y
divide by 20
210/20 =y
21/2 = y
Answer:
Bill is 9.80 km apart from Concert
Step-by-step explanation:
It's given in the question,
m∠B = 75°
m∠C = 45°
By triangle sum theorem,
m∠A + m∠B + m∠C = 180°
m∠A + 75° + 45° = 180°
m∠A = 180° - 120°
m∠A = 60°
By sine rule,
BC = 
= 9.80 km
Therefore, Bill is 9.80 km apart from Concert.
Answer:
0.35
Step-by-step explanation:
P(0) = 348/1000
0.348
0.35 to the nearest hundredth
137.1
You would find the area of the semi circle by using the circle formula and dividing by 2, which would be 8
Then find the area of the rectangle, which would be 112.
Since you didn't answer i think JL is x+26
JK=x+26-x-22=4
KM=19
JM=4+19=23
