For the right triangles below, find the exact values of the side lengths a and c. If necessary, write your responses in simplified radical form.

Answers

Answer:

First triangle: [tex]a = 5\sqrt{2}[/tex], second triangle: [tex]c = \frac{8\sqrt{3}}{3}[/tex]

Step-by-step explanation:

In the first triangle, the value of [tex]a[/tex] is equal to the following trigonometric relation:

[tex]a = \frac{5}{\cos 45^{\circ}}[/tex]

[tex]a = \frac{5}{\frac{\sqrt{2}}{2} }[/tex]

[tex]a = \frac{10}{\sqrt{2}}[/tex]

[tex]a = \frac{10\sqrt{2}}{2}[/tex]

[tex]a = 5\sqrt{2}[/tex]

In the second triangle, we obtain the value of [tex]c[/tex] is equal to the following trigonometric relation:

[tex]c = 8\cdot \tan 30^{\circ}[/tex]

[tex]c = 8 \cdot \left(\frac{\sin 30^{\circ}}{\cos 30^{\circ}} \right)[/tex]

[tex]c = 8\cdot \left(\frac{\frac{1}{2} }{\frac{\sqrt{3}}{2} } \right)[/tex]

[tex]c = \frac{8}{\sqrt{3}}[/tex]

[tex]c = \frac{8\sqrt{3}}{3}[/tex]

Step-by-step explanation:

Answer:

26

Step-by-step explanation:

Let the number be x.

x = [tex]\dfrac{52}{2}[/tex]

x = 26

Jerry is 5 years less than half of Mary's age. The sum of their ages is 22. How old is each person?

Answers

Answer:

Mary= 18

Jerry = 4

Step-by-step explanation:

Half of mary's age is 9, minus 5 =4.

18+4=22

Answer:

Equation 1: m/2 - 5 = j

Equation 2: m + j = 22

Mary's age: 18

Jerry's age: 4

Step-by-step explanation:

m/2 - 5 = j

18/2 - 5 = j

9 - 5 = 4

m + j = 22

18 + 4 = 22

22 = 22

Describe how to solve x−6=−12.

Answers

Answer:

See explanation.

Step-by-step explanation:

You have to use the inverse operation of -6 to get x by itself. So you have to add 6 to each side to get rid of the -6. And -12+6=-6. So, x=6.

Answer:

X is -6

Step-by-step explanation:

You have to add 6 to both sides like -6+6 and -12+6

-12+6=-6 which is the answer because -6-6 is -12
