Answer:
1. 23.0 cm
2. 21.0 ft
3. 31.0 yd
Step-by-step explanation:
1. 30/sin110 = RT/sin46
RT = sin46 × 30/sin110
RT = 22.96516279
2. Angle A = 180 - 61 - 53 = 66°
24/sin66 = AB/sin53
AB = sin53 × 24/sin66
AB = 20.98116966
3. 18/sin28 = HP/sin54
HP = sin54 × 18/sin28
HP = 31.01850475
The answer for this is 78
Answer:
Distance = 5
Step-by-step explanation:
x2 = 3
y2 = 1
x1 = 7
y1 = -2
=> d = Square root of (3 - 7)^2 + (1 + 2)^2
=> d = Square root of (-4)^2 + (3)^2
=> d = Square root of 16 + 9
= d = Square root of 25
d = 5
