Step-by-step explanation:
Use Sine rule.
Angle A + angle B + angle C = 180 (sum of angles in triangle)
Angle A + 90 + 42 = 180
Angle A + 132 = 180
Angle A = 180 - 132
= 48
Answer:
B. 14 m sq.
Step-by-step explanation:
Area for a triangle
A = W times H times 1/2
4 times 7 = 28
28/2 = 14
Answer:
m<E = 44°
Step-by-step explanation:
If the figures are congruent, therefore their corresponding angles would also be equal to each other.
Thus, angle K corresponds to angle E.
Since m<K = 44°, therefore,
m<E = 44°
Answer:
$2.22 i think
Step-by-step explanation:
Step One
Find the cost of one bottle
12 bottles cost 9.25 pounds.
1 bottle costs x
12 / 1 = 9.25/x Cross multiply
12*x = 1 * 9.25 Divide by 12
x = 9.25 / 12
x = 0.77
Remark
0.77 pounds sterling = 77 pennies
Step Two
find the profit on the sale of one bottle
100 - 77 = 23 pennies
Step Three
Find the % profit on one bottle.
% Profit = (profit on one bottle / Cost of 1 bottle.) * 100%
% Profit = (23 / 77) * 100
% Profit = 29.87% <<<<<<<< Answer.
