Which of the following sets of measurements can form exactly 1 triangle..1)a=12,b=27, A=37 degrees..2)a=11,b=15,A=36 degrees.3)a=6, b=10,A=42 degrees..4)a=7, b=5, A=19 degrees

the aswere is the one with all 8's and the second one is with the 10,8 and 6

step-by-step explanation:

the number of the people going.

step-by-step explanation:

the cost to buy one movie ticket is $7. if the total cost for the movie is a function of how many people go, then the input is : the number of the people going.

d) by the cross product property, ab^2 = bc multiplied by ad

step-by-step explanation:

we are given

in the given triangle abc

angle a is 90° and segment ad is perpendicular to segment bc

we can see that

triangle(abc) and triangle(abd) are similar because they have common side and same angle (90 degree)

so, triangles(abc) and abd are similar

since, they are similar

so, the ratio of their sides must be equal

we get

now, we can cross multiply

and we get

so, this could be step to prove it
