Answer:
9.2
Step-by-step explanation:
w = 4 cm
recall that the area of a triangle is given by
A = (1/2) x base length x height
we are given:
A = 10 cm²
base length = 5 cm
height = w
substituting the values above into the equation,
10 = (1/2) x 5 x w
20 = 5w
w = 20/5
30.7777
so in terms of x we write
