Answer:
so the labelled angles are 30 and 90, but it only shows one 90. In fact there are 4 angles of 90. The marked 90 then the vertical angle and the complementary angles. All triangles equal 180 so the given 30 and 90 are taken from the 180.
180 -30-90= 60
But y is the opposite of the 30 which makes y=30
so that leaves x = 60
y=30 and x=60
Answer:
Volume of green house = 54 m³
Step-by-step explanation:
Given:
Base = 3m x 9m
Height of house = 2 m
Find:
Volume of green house
Computation:
Volume = lbh
Volume of green house = 3m x 9m x 2m
Volume of green house = 54 m³
20% of x=6
20/100 of x=6
20x= 600
x=30
38% of 30=11.4
Answer:
2
Step-by-step explanation:
2x5=10
Answer:
Let's assume the number be 100.
According to the problem , 100 is increased by 100%.
So, new number will be 100+100=200
Now 200 will decreased by 20%.
So, 20% of 200= 0.20*200= 40.
So, again the number has been changed into 200+40=240.
So, x=240
