Simplify 2:4
you get 1:2
this means the larger is two times the smaller.
well, we have to use a system of equations.
we know two supplementary angles add up to be 180°.we can create our first equaition, using
smaller angle + larger angle = 180
s + l = 180
we can create our second equation using
two times the smaller = larger
2s = l
our two equations are:
2s = l
s + l = 180
now that we have the two equations, we can solve using subsitution to isolate the variable.
s + l = 180
s + (2s) = 180
simpify.
3s = 180
s = 60
the smaller angle has a value of 60.
now, remember that the larger angle is two times the smaller.
60 x 2 = 120
smaller angle: 60
larger angle: 120
we know this is correct because we know the smaller is 1/2 or 1:2 or 2:4 times the bigger, and the two angles add up to be 180 (60 + 120)
hope this helps and have a great day!
Answer:
the anser from what i see should be option 1
Step-by-step explanation:
The reason why i say this is because number 1 is linear which means it is just multipying but your multiplying and adding and its not option 3 because question 5 said the questions started at 1
I think the correct answer among the choices given is option D. The base of the sail can be calculated using the expression 7 cot 50°. The cotangent function of an angle in a triangle is the adjacent side of the angle divided by the opposite side of the angle. From the given data, this is the best function to use.
Substitute the x and y values
Simplify
Subtract 30 from both sides
Simplify
Divide both side by (-2)
Simplify
