Answer:
e°=100°
Step-by-step explanation:
Sum of angles in a triangle= 180°
70°+30°+x°=180°
100°+x=180
Collect like terms
x°=180-100
x°=80°
e° is an exterior angle
exterior angle =180- interior angle
180°- x°
180°- 80°
=100°
e°=100°
The ratio of 50% content to 25% content is
.. (40-25) : (50-40) = 15:10 = 3:2
There is a total of 5 "ratio units" in this ratio, so each is representing 35 kg/5 = 7 kg of alloy.
21 kg of 50% alloy and 14 kg of 25% alloy should be used.
