Answer:
x=69° y=69°
Step-by-step explanation:
Angle x is an alternate angle so it is equal to the angle above it (69)
Angle y is in a co-interior angle so you do the equation 180-111 which equals 69°
Area of ∆=1/2bh
80yd^2=1/2(b)(10yd)
80yd^2=5yd(b)
80yd^2÷5yd=b
16yd=b
Solution:
Let the volume (in litres) of acids used be:
x1=amount of 25% acid
x2=amount of 40% acid
