Answer:
71 degrees
Step-by-step explanation:
its an isosceles triangle so those angles are equal. Draw it out if that helps you.
Answer:
5/13
Step-by-step explanation:
According to SOH CAH TOA
cos theta = adj/hyp = -12/13
Get the opposite using pythagoras theorem
13^2 = (-12)^2 + opp^2
169 = 144 + opp^2
opp^2 = 169-144
opp^2 = 25
opp = 5
Get sin θ
sin θ = opp/hyp
sin θ = 5/13
hence the value of sin θ is 5/13
You can find the area of a triangle by using this equation:
Area=(1/2)base x height
If you have the measurement for the bottom part of the sandwich, then you have your base. If you have the height of the sandwich then you have the height. Since the triangles are congruent when you find the area of one triangle, you are finding the area of the other triangle. To combine the areas of the triangles, just multiply the area of one triangle by 2.
So what you do you divide 8000 by 30 and should get 266.6 gallons were wasted
