Answer 1

Answer:

I am pretty sure that it's C

Step-by-step explanation:

you need to do a^2+b^2=c^2

Answer 2

Answer:

A

Step-by-step explanation:

Use a^2 + b^2 = c^2 in each case.

A.

9^2 + 12^2 = 15^2

81 + 144 = 225

225 = 225 True

Right triangle

B.

2^2 + 6^2 = (sqrt(38))^2

4 + 36 = 38

40 = 38 False

No right triangle

C.

3^2 + 9^2 = (sqrt(91))^2

9 + 81 = 91

90 = 91 False

No right triangle

Answer:

m<5 = 133°

m<8 = 47°

Step-by-step explanation:

if <2 = 47°, and <5 is supplementary to <2, that means that together they both have to equal 180°. So, to get the measure of <5, you need to do 180 - 47 to get <5 = 133°.

Now, <5 (133°) is supplementary to <8, so they both have to equal 180° together. So, you must do 180 - 133 to get <8 = 47°. Or, another way to get <8 is to notice that <2 and <8 are alternate interior angles, which means they equal the same amount. So if <2 = 47°, then so does <8.

The ages of Aman and Arun are in the ratio 5:7. Four years later the sum of their ages will be 56 years. What are their present ages

Answers

Answer:

Aman's age = 20, Arun's age = 28

Step-by-step explanation:

Let [tex]x[/tex] = Aman's age

Let [tex]y[/tex] = Arun's age

- - - -

[tex]x+4+y+4=56[/tex] (Sum of their age is 56 after 4 years in the future)

[tex]x+y+8=56[/tex]

[tex]x+y=48[/tex]

[tex]\frac{x}{y} = \frac{5}{7}[/tex] (Ages are in the ratio 5:7)

[tex]x=\frac{5}{7}y[/tex]

Now, we can use substitution to find for Arun's age:

[tex]x+y=48[/tex]

[tex]\frac{5}{7}y+y=48[/tex]

[tex]\frac{12}{7}y=48[/tex]

[tex]y=28[/tex]

∴ Arun is [tex]28[/tex]

To find for Aman's age, we can use substitution:

[tex]x+y=48[/tex]

[tex]x+28=48[/tex]

[tex]x=20[/tex]

∴ Aman is 20

Hope this helps :)
