Area of a triangle is 1400 cm² the base of the triangle is 5 times the height what is the height of the triangle

≈23.66

Step-by-step explanation:

Height ---> x

base ---> 5x

Formula for area of triangle: (base*height)/2

((5x)(x))/2 = 1400

/2 = 1400

= 1400 · 2 = 2800

= 2800/5 = 560

x= √560 ≈ 23.66

the answer to the question is a

step-by-step explanation:

it has the same slope and the same y-intercept.

y + 11 = -7/9(x - 18)

y + 11 =-7/9x + 14

b

y = -7/9x + 3

y-intercept (0, 3)
