Answer: Equation that represents this problem is [tex]2b+5=74[/tex]
The base of the triangle is 34.5 mm.
Step-by-step explanation:
Let b represents the base length of the triangle in mm.
Given : The height of a triangle is 5 more than double the base length.
i.e. Height = 2b+5
If the height of the triangle is 74 mm, then the equation that represents this problem is [tex]2b+5=74[/tex]
To find b , first subtract 5 from both sides of the equation, we get
[tex]2b=69\\\\\Rightarrow\ b=34.5[/tex] [Divide both sides by 2]
Hence, the base of the triangle is 34.5 mm.
