Answers

Answer:

98

Step-by-step explanation:

with the rule "corresponding angles are equal" it means that "d" and "f" are equal.

and since "f" is on the other side of 82, on a straight line, you can calculate "f".

82 and "f" would have to add up to 180' since they are on a straight line.

So you do 180 - 81 = f

and get 98.

and since "f = d"

d = 98 degrees

Answers

Answer:

A - eight feet

Step-by-step explanation:

20 character rule can be dumb sometimes

The Pythagoras is the sum of the square of two sides is equal to the square of the longest side. The height of the house is 12 feet, then the correct option is B.

What is a right-angle triangle?

It is a type of triangle in which one angle is 90 degrees and it follows the Pythagoras theorem and we can use the trigonometry function.

Miguel places his 13-foot ladder 5 feet from the edge of his house.

Then the height of the house is given by the Pythagoras theorem.

P² = H² - B²

P² = 13² - 5²

P² = 169 - 25

P² = 144

P = 12

Then the height of the house is 12 feet.
