Given right triangle GYK, what is the value of tan(G)?

Ludmilka [50]

Answer:

The value of tan(G) in the right triangle GYK Is $\sqrt{3}$

Step-by-step explanation:

Given

Measure of angle at $G=60^{\circ}$

Measure of angle at $Y=30^{\circ}$

Measure of angle at $K=90^{\circ}$

To find:

$\tan (G)=?$

Solution:

In trigonometry we know that

$\tan G=\frac{\sin G}{\cos G}$

$G=60^{\circ}$

So,

$\sin (60)=\frac{\sqrt{3}}{2}$

$\cos (60)=\frac{1}{2}$

Substituting in the formula we have,

$\tan G=\frac{\frac{\sqrt{3}}{2}}{\frac{1}{2}}$

$\tan G=\frac{\sqrt{3}}{2} \times \frac{2}{1}$

$\tan G=\frac{\frac{\sqrt{3}}{2}}{\frac{1}{2}}$

$\tan G=\sqrt{3}$

Result:

Thus the value of $\tan G=\sqrt{3}$

Jason hiked 15.6 kilometers on Saturday, 18.1 kilometers on Sunday,and 22.7 kilometers on Monday. How many kilometers did he hik

Nadya [2.5K]

Answer:

The correct answer is D. 56.4

Step-by-step explanation:

1. Let's review the information given to us for solving the question:

Kilometers hiked by Jason on Saturday = 15.6

Kilometers hiked by Jason on Sunday = 18.1

Kilometers hiked by Jason on Monday = 22.7

2. How many kilometers did he hike during the three days?

Total of kilometers hiked by Jason = Kilometers hiked by Jason on Saturday + Kilometers hiked by Jason on Sunday + Kilometers hiked by Jason on Monday

Total of kilometers hiked by Jason = 15.6 + 18.1 + 22.7

Total of kilometers hiked by Jason = 56.4

The daily gazzette has 25 companies that pay for advertising each month the newspaper wants to increase its advertisers by 5 eac

Vikentia [17]

Answer: 25+5m =50

Step-by-step explanation:

Hi, to answer this question we have to write an equation:

The actual number of companies that pay for advertising each month (25) plus the product of the companies added per month (5) and the number of months (m) must be equal to the actual number of advertisers multiplied by 2 ( since they want to double it ).

Mathematically speaking:

25 +5m = 25 (2)

25+5m =50

Feel free to ask for more if needed or if you did not understand something.
