Answer:

14 cm²

Step-by-step explanation:

Obtuse angle: more than 90° and less than 180°

The formula for the area of an obtuse triangle is the same as that for any triangle:  

  • area of a triangle = 1/2 x base x height

Therefore, given:

  • base = 4 cm
  • height = 7 cm

⇒ area = 1/2 x 4 x 7 = 14 cm²

4. What is the axis of symmetry for h(x) = 19(x – 5)^2 + 6
tester [92]

Answer:

x = 5

Step-by-step explanation:

y = a(x - h)² + k

(h, k ) are the coordinates of the vertex and a is a multiplier

h(x) = 19(x - 5)² + 6 ← is in vertex form

with vertex (h, k ) = (5, 6 )

The axis of symmetry is a vertical line passing through the vertex

with equation x = 5
