Answer:
it is 4/3
Step-by-step explanation:
because tan(B) = opposite/adjacent
Write and solve an equation of ratios:
vinegar 0.25 x
------------ = --------- = -----------
dressing 1.00 2 cups
Cross multiply. We get 0.5=x. Sue needs to use 1/2 cup of vinegar and 1 1/2 cups of the other ingredient(s).
Answer:
We see that the big triangle is an equilateral triangle, so all its angles will measure 60°. Therefore x° will be 60° - 30° = 30°, as he's the base angle of an isosceles triangle having the other base angle of 30°. y will simply be 180° - 60° (remembering that the sum of the angles in a triangle is always 180°).
4x + 2 = 62
4x = 62 - 2
4x = 60
x = 60/4
x = 15 <===
12y = 144
y = 144/12
y = 12 <===
alternate interior angles are congruent
F(3)=4(3)+3(exchange all “x” for 3
f(3)=12+3(multiply 4 times 3)
f(3)=15(add 3 to 12)
