Answer:

The value of b is 21

Step-by-step explanation:

29=√20^2+b^2

or, 29=√400+b^2

or, 841=400+b^2

or, 841-400=b^2

or, √441=b

b=21

Which angle measure in the triangle shown is the largest?<br><br> A.) B.) C.) D.) Not Possible
alex41 [277]
You haven't provided neither the diagram nor the options.
Therefore, I cannot provide an exact answer, however, I will try to help you with the concept.

<u>For a triangle, the measure of each angle is proportional to the length of its opposite side.</u>
<u>This means that:</u>
1- The largest angle is the angle opposite to the longest side
2- The smallest angle is the angle opposite to the shortest side

Since you are looking for the largest angle, pick the one facing the longest side

<u>Some tips and tricks:</u>
<u>1- In a right angle triangle</u>, we know that the hypotenuse is the longest side, therefore, the largest angle would be the right angle
<u>2- In an obtuse triangle</u>, the largest angle is simply the obtuse angle itself (the one whose measure is greater than 90)
<u>3- In equilateral triangle</u>, all three angles are equal

Hope this helps :)

Find all angles and pls show steps ​
Ghella [55]

Answer:

Both angles have a measure of 134degrees, y = 27degrees.

Step-by-step explanation:

As per what is given in the problem:

There are 2 parallel lines, both are intersected by a transversal.

Remember the theorem, when two parallel lines are intersected by a transversal, then the alternate exterior angles are congruent.

The is meanse that:

3y + 53 = 7y - 55

Solve using inverse operations:

3y + 53 = 7y - 55

     +55         +55

3y + 108 = 7y

-3y            -3y

108 = 4y

/4      /4

27 = y

Now, substitute back in to find the value of the angle:

3y + 53

y = 27

3 ( 27 ) + 53

81 + 53

= 134

Since the angles are alternate exterior, they are congruent, hence both angles have a measure of 134degrees.
