Answer:
Angle B = 47.3°
Step-by-step explanation:
We are to find Angle B
b = 6.8cm
C = 70°
c = 8.7cm
We solve using Sine rule
b/sin B = c/ sin C
6.8/sin B = 8.7/sin 70
Cross Multiply
sin B × 8.7 = 6.8 × sin 70
sin B = 6.8 × sin 70/8.7
B = arc sin ( 6.8 × sin 70/8.7)
B = 47.26265°
Approximately to 3 significant figures
= B = 47.3°
The ratio between what harry pays to what his dad pays is given as 2:3.
We know that harry's dad paid <span>£</span>52.2, therefore, we can use cross multiplication to find the amount that Harry paid as follows:
harry paid = 52.2 * (2/3) = £34.8
The total cost of the meal would be the addition of what they both paid, this means that:
total cost of meal = 52.2 + 34.8 = £87
