Area of the triangle = 1/2 x base x height
Let height be "h"
60 = 1/2 x 20 x h
60 = 10h
h = 6 cm
Height of the triangle = 6 cm
Answer:
hello
Step-by-step explanation:
Answer:
A
Step-by-step explanation:
The equation of a parabola in vertex form is
y = a(x - h)² + k
where (h, k) are the coordinates of the vertex and a is a multiplier
Here (h, k) = (2, 1), thus
y = a(x - 2)² + 1
To find a substitute (1, 0) into the equation
0 = a(1 - 2)² + 1
0 = a + 1 ( subtract 1 from both sides )
a = - 1
Hence
y = - (x - 2)² + 1 or
y = 1 - (x - 2)² → A
