V = 12 × 2 × 3 = 72 cm3
Hope this helps!
Step-by-step explanation:
4x(8+5)+9
=52x+9
=52x+9
Description:
The first step is to simplify the equation provided. So in this case the equation is 4 x (8 + 5) + 9. After that you will get your answer as =52x+9. So in this case 4 x (8 + 5) + 9 = =52x+9.
Answer: =61

Answer:
The answer to your question is 14° and 76°
Step-by-step explanation:
Data
leg 1 = x
leg 2 = x/4
angle 1 = ?
angle 2 = ?
Process
To solve problem use trigonometric functions. We must use the trigonometric function that relates both legs (tangent).
tangent Ф = Opposite side / Adjacent side
-Substitution
tan Ф = (x/4) / x
-Simplification
tan Ф = x / 4x
tan Ф = 1/4
- Find Ф
Ф = tan⁻¹(1/4) = 14°
- Find the other acute angle
The sum of the internal angles in a triangles equals 180°
Ф + Ф₁ + 90° = 180
-Solve for Ф₁
Ф₁ = 180 - 90 - 14
-Result
Ф₁ = 76°
Answer:
