Describe two ways that an exterior angle of a triangle is related to one or more of the interior angles.

1 answer:

4 0

Well, an interior angle plus an exterior angle has to equal 180°. Also, the sum of the interior angles is represented by this formula: [-2 + n]180, whereas the sum of the exterior angles all add up to 360°, and is represented by this formula: 360/n [let "n" represent the number of sides in every polygon].

Find the indicated limit, if it exists.(7 points)

Alecsey [184]

Answer:

Step-by-step explanation:

The left hand limit is when we approach zero from left. We use the function on this domain in finding the limit.

$\lim_{x \to 0^-} f(x)=7-x^2$

$\lim_{x \to 0^-} f(x)=7-(0)^2=7$

The right hand limit is

$\lim_{x \to 0^+} f(x)=10x+7$

$\lim_{x \to 0^+} f(x)=10(0)+7=7$

Since the left hand limit equals the right hand limit;

$\lim_{x \to 0} f(x)=7$

Find each percent increase. Round to the nearest percent. From 24 teachers to 30

DedPeter [7]

The percent increase is 25 %

Solution:

Given that we have to find the percent incraese

From 24 teachers to 30

The percent increase between two values is the difference between a final value and an initial value, expressed as a percentage of the initial value.

The percent increase is given as:

$\text { percent increase }=\frac{\text { final value - initial value}}{\text { initial value }} \times 100$

Here, initial value = 24 and final value = 30

Substituting the values in above formula, we get

$Perecnt\ Increase = \frac{30-24}{24} \times 100\\\\Perecnt\ Increase = \frac{6}{24} \times 100\\\\Perecnt\ Increase = 0.25 \times 100\\\\Perecnt\ Increase = 25$

Thus percent increase is 25 %

Answer:

Above,please mark as brainliest

Step-by-step explanation:

Catherine:x

Gabe:x+6

Juan:3(x+6)=3x+18

(3x+18)+(x+6)+x=149

5x+24=149

5x=125

x=25

Catherine:25

Gabe:31

Juan:93

Check:93+25+31=149
