Answer:
50
Step-by-step explanation:
x = √30² - 18² = √576 = 24
tan A = 18/24 = 3/4
∠A = ∠B
tan B = tan A = 24 / y = 3 / 4
y = (24 x 4) / 3 = 32
Z = y + 18 = 32 + 18 = 50
X=4 and y=6
For this, you should use simultaneous equations

Answer:
32000 tonnes
Step-by-step explanation:
Given there was a 20% reduction last year from a total of 40000 tonnes .
20% /100% x 40000
0.2 x 40000
8000tonnes
Therefore, previous year’s excerpt = 40000 - 8000
32000tonnes
In this problem the big angle will be equal to two times the smaller angle so the correct expression is:

Now we can rewrite the equation so:
