If you wish to show that two triangles are similar, which statement(s) is correct?
you may choose more than one correct answer.

a)it is enough to show that one pair of corresponding angles is congruent.
b)it is enough to show that two pairs of corresponding angles are congruent.
c)it is enough to show that two pairs of corresponding sides are in the same ratio.
d)it is enough to show that all three pairs of corresponding sides are in the same ratio.
e)it is not enough to have information about only sides or only angles.

answer:  

step-by-step explanation:

here x represents the height of the pole,

and, the height of the shadow of the pole is 12 feet.

also, the angle of elevation from the top of the pole is 40°,

therefore,

by the low of sine,

which is the required equation for finding the value of x,

step-by-step explanation:

abc

5x + 5

step-by-step explanation:

you should always add the diagrams and graphs we cannot see. this particular question is kind of borderline because we can make a graph for you.

(f + g)x = -x^2 +3x + 5 + x^2 + 2x

(f + g)x = 5x + 5

the graph of z = 5x + 5 is shown below. always use desmos when in doubt.
