Answer:
a = 15
Step-by-step explanation:
Given
3a + b = 54 ← substitute b = 9
3a + 9 = 54 ( subtract 9 from both sides )
3a = 45 ( divide both sides by 3 )
a = 15
Answer:
it should be B.
Step-by-step explanation:
Answer:
<u>-289 degrees</u>
Step-by-step explanation:
You are looking for what is called <u>Coterminal Angles</u>.
To find a coterminal angle between 0 and 360 you <u>add or subtract</u> 360.
- In this case, we subtracted 360 from 71
- 71 - 360 = -289
- tan(-289) = 2.90
- If TAN 71 = 2.90 and TAN -289 = 2.90, you know -289 is your answer.

Answer:
x = 3
Step-by-step explanation:
Given:
- The volume of the triangular prism : 54 cubic units
- The base length: 4 unit
- The height of the base: x
- The height of the prism : 3x
As we know that, the formula used to find out the volume of a triangular prism is:
V = 1/2 * The base length * The height of the base * The height of the prism
<=> V = 1/2*4*x*3x
In this question we have V = 54 cubic units
<=> 1/2*4*x*3x = 54
<=>
= 9
<=> x = 3
