Area of base of Triangle
= ½(15)(5)
= 37½ units²
Area of sides of Triangles
= (15 × 9) + ½(17)(15)
= 262½ units²
Total surface area of Triangle
= 262½ + 37½
= 300 units²
Answer:
3x - y + 7 = 0
Step-by-step explanation:
The given point is , ( -4 , -5) and the slope is 3. The point slope form is ,
=> y - y₁ = m( x - x₁)
=> y - (-5) = 3 { x - (-4) }
=> y +5 = 3( x + 4 )
=> y + 5 = 3x + 12
=> 3x - y + 12 - 5 = 0
=> 3x - y +7 = 0
<h3>

15 meters should be about right. hope this helped
