Consider the two triangles. Triangles A B C and H G I are shown. Angles A C B and H I G are right angles. The length of side A C
zheka24 [161]

Answer:

Both are similar by SAS similarity.

This SAS similarity is equivalent to the congruence.

Step-by-step explanation:

Step 1:

To prove that ACB and HIG as similar triangles.

We have to look upon the corresponding sides.

SAS= Side angle sides , there the angle must be in between two sides.

\angle ACB = \angle HIG

Lets work on the corresponding sides.

IG/AC = IH/AC

\frac{9}{15} = \frac{12}{20}

Reducing each to lowest form, we divide numerator and denominator by 3 for the 1st fraction and by 4 for the 2nd fraction.

We have

\frac{3}{5} = \frac{3}{5}

Both sides are equal.

So its proved that both are similar with SAS similarity theorem.

pedro earned gross income of 35200 last year. if he took the standard deduction of 5450 and one exemption of 3500, what was his
Elenna [48]

Answer:

33250

Step-by-step explanation:

Pedro had earned a gross income of 35200 last year.

So, the gross income of Pedro for the current year will also be 35200.

But, this year he has taken the standard deduction of 5450.

Hence, his current year's income will be reduced to (35200-5450)= 29750.

Again, in the current year, he got an exemption of 3500.

Therefore, the net taxable income of Pedro for the current year will become (29750+3500) =33250. (Answer)
