Answer:
∠A = 88°
∠B = 92°
∠C = 88°
∠D = 92°
Step-by-step explanation:
∠A + ∠B = 180°
(2x + 4) + (3x - 34) = 180
reduce:
5x - 30 = 180
5x = 210
x = 42
∠A = 2(42) + 4 = 88°
∠B = 3(42) -34 = 92°
∠C = ∠A = 88°
∠D = ∠B = 92°

Step-by-step explanation:
Answer:
100
Step-by-step explanation:
Male students take up 100%-44% = 56% of the whole school.
Let x be the total number of students.
56/x = 56%
56/x = 56/100
x = 100
Therefore there are 100 students in total.
