From that picture...you already have 3 right angles so the 4 th is also a right angle of 90 degrees
Answer:
30 is 20% of 150 i.e. 20% of total 150 students in the marching bank play the trumpet.
Step-by-step explanation:
Draw two number lines:
- One number line to represent number of students from 0 to 150. For convenience, divide the number line into intervals of 15 so that 30 is also present on the line.
- Second number line to represent percentage and divide it in intervals from 1 to 100.
Now, place the other number line just below the other number line and draw a vertical line as shown the attached figure.
We find out that 30 is at 20% of 150.
It means that 20% (30 of total 150) of total 150 students in the marching band, play trumpet.

Answer:
x = -2/9
Step-by-step explanation:
27x = 9x − 4
Subtract 9x from each side
27x-9x = 9x-9x − 4
18x = -4
Divide each side by 18
18x/18 = -4/18
x = -4/18
Divide the top and bottom by 2
x = -2/9
Answer:
24.36
Step-by-step explanation:
tan(angle) = opposite/adjacent
tan(38) = 19/x
x = 19/tan(38) = 19/0.78 = 24.4
