How do you explain how to get h(t)=7(t-25)
Nutka1998 [239]
Hey There! :)

To Solve for t.
h(t)=7(t-25)
Distribute the brackets.
h(t)=7*t-7*25
h(t)=7t-175
Subtract 7t from both sides.
(h(t))-7t=(7t-175)-7t
(h(t)-7t=-175
h*t-7t=-175
Factor out variable, t.
t(h-7)=-175
Divide both sides by h-7.
(t(h-7))/h-7=(-175)/h-7
t=-175/h-7

Hope this helps!

Hitman42 [59]

Answer:

8.5 cm

Step-by-step explanation:

Angles of the triangle:

  • x+2x+3x= 180
  • 6x= 180
  • x= 30
  • 30°, 60° and 90°

Right triangle as it has 90° angle

Sides are a, b and 19 cm

  • sin 30°= a/19 ⇒ a= 19 sin 30°= 19*0.5= 8.5 cm  = shortest side
  • sin 60°= b/19 ⇒ b= 19 sin 60°= 19*0.866= 16.45 cm
