A⋅3 = -30<br> i need answers anybody know?

Given that ∠A≅∠B , Gavin conjectured that ∠A and ∠B are complementary angles.

Pani-rosa [81]

Given ∠A≅∠B which means A and B are congruent, so A and B should have same value.

and also given that A and B are complementary angles which mean ∠A+∠B=90°

Now to find counterexample to Gavin's statement, we should find two angles satisfying ∠A≅∠B and contradicting ∠A+∠B = 90°

Let us check given options:-

A) since A and B are not equal, it is contradicting the first statement itself.

B) Here ∠A=25 = ∠B , hence it is satisfying congruent condition.

Let us check they are complementary or not by adding them.

∠A+∠B = 25°+25° = 50° ≠90°

Which means it is an counter example to Gavin's statement which tells that two congruent angles need not be complementary.

C) since A and B are not equal, it is contradicting the first statement itself.

D) Here ∠A=45°=∠B, hence it is satisfying congruent condition.

And ∠A+∠B = 45°+45° = 90°

Hence this is not an counter example.

Can anyone help me ?<br> Find the missing angle measure.

jeyben [28]

Answer:

x° = 99°

Step-by-step explanation:

The polygon is a hexagon and the sum of its internal angles is:

$180(n-2)=180(6-2)=180(4)=720^{0}$

subtract the 5 known angles:

$x^{0} =720-145-164-59-132-121=99^{0}$

Hope this helps

A back-to-back stem-and-leaf plot compares two data sets by using the same stems for each data set. Leaves for the first data s

tester [92]

The true statements are:

At Law Firm A, the lowest salary was $90,000 and the highest salary was $203,000
At Law Firm B, the lowest salary was $90,000 and the highest salary was $195,000
There are 30 lawyers in Law Firm A, and 32 lawyers in Law Firm B

<h3>How to calculate the lowest salaries</h3>

To calculate the lowest salaries, we simply consider the smallest stem and the smallest leaf of both plots.

From the figure, we have the following highlights

The least stem and leaf of both Law Firms plot are 90 and 0

Hence, the lowest salary of both law firms is $90,000

<h3>How to calculate the highest salaries</h3>

To calculate the highest salaries, we simply consider the highest stem and the highest leaf of both plots.

From the figure, we have the following highlights

The highest stem and leaf of Law Firm A are 20 and 3
The highest stem and leaf of Law Firm B are 19 and 5

Hence, the highest salary of law firm A is $203,000, while the highest salary of law firm B is $195,000

<h3>The number of lawyers in both firms</h3>

This is the number of leaves in both plots

Hence, there are 30 lawyers in Law Firm A, and 32 lawyers in Law Firm B
