Answer:

2.9 units

Step-by-step explanation:

Here the leg lengths are x and 7.7 and the one given angle is 21 degrees.

Think:  which trig function incorporates both the length of the side opposite the 21 degree angle (x) and the vertical side (7.7)?  It's the tangent function:

tan Ф = opp / adj

To be clear:  the side adjacent (next to) the 21 degree angle is 7.7 units in length and the side opposite this angle is x.

Then we have tan 21 degrees = opp / adj = x / 7.7

and so 7.7(tan 21 degrees) = 7.7(03839) = 2.96 or (to one decimal place) 2.9

Basic Definitions of Geometry


A collinear set of points is a set of points all of which lie on the same straight line.
A noncollinear set of points s a set of three or more points that do not all line on the same straight
line.
A Line has no end points.
A Ray has one end point.
. Line Segment has two end points
Congruent segments are segments that have the same measure.
The Midpoint of a line segment is a point of that line segment that divides the segment into two
congruent segments.

The Bisector of a line segment is any line, or subset of a line that intersects the segment at the midpoint.
An Angle is a set of points that is the union of two rays having the same endpoint.

identify a two-digit dividend that will result in a quotient with a remainder 1 when the divisor is 4
Afina-wow [57]
17, 21, 25, etc. because when you divided 4 by any of these numbers you will get your answer with a remainder of 1. For example, 17/4 is 4 R.1 because 4 times 4 is 16, then you will have one left over. (At my school you always go to a decimal not a remainder)

Which of the following statements is not true of deductive reasoning? It is used when you solve an equation in algebra. It is us
erastova [34]

<u>Answer:</u>

"It is used when you solve an equation in algebra" is the untrue statement.

<u>Step-by-step explanation:</u>

"It is used when you solve an equation in algebra."

When you solve an algebra problem, you are not using deductive reasoning. You are using the information in front of you to correctly answer.

"It is used to make broad generalizations using specific observations."

This is exactly what deductive reasoning is, you are making generalizations and coming up with your own conclusions through observation.

"It is used to prove basic theorems."

This is also true, you can use deductive reasoning by using your specific observations and drawing conclusions to prove the theorems.

"It is used to prove that statements are true."

Using your own observations, you can draw your own conclusions to prove what you are saying is factual.

Which set of numbers could represent the lengths of the sides of a right triangle?
vitfil [10]

in this problem what you are really looking for is which of these sets is a pathagorean triple. That means it will solve the pathagorean theorem. (a sqaured + b squared = c squared) c is always going to be the largest number or the hypotenuse. if you plug all the number sets into the theorem, only one works and that is 7, 24, 25 which is your answer.
