A triangle has side lengths of 7, 24, and 26. Is the triangle right, acute, or obtuse? a. right c. obtuse b. acute Please select

horrorfan [7]

Answer:

Option C. Obtuse

Step-by-step explanation:

we know that

Applying the Pythagoras Theorem

If $c^{2}=a^{2} +b^{2}$ ----> is a right triangle

If $c^{2}>a^{2} +b^{2}$ ----> is a obtuse triangle

If $c^{2}$ ----> is an acute triangle

where

c is the greater side

<em>Verify</em>

$c^{2}=26^{2}= 676$

$a^{2} +b^{2}=7^{2} +24^{2}=625$

therefore

$676>625$

$c^{2}>a^{2} +b^{2}$ -----> is a obtuse triangle

What is the angle measure of 2x+1°

Ray Of Light [21]

Answer:

25 degrees

Step-by-step explanation:

Haha, awesome! Just did a problem like this!

All angles add up to 180, so set it up like this:

2x + 1 + 5x + 5 + 90 = 18

Combine like terms.

7x + 96 = 180

7x = 84

x = 12

Plug x back into 2x + 1

2(12) + 1

24 + 1

= 25 degrees

While we're at it...

5(12) + 5

60 + 5

= 65 degrees (for the other angle)

25 + 65 + 90 = 180

Math checks out & we're good to go!

Hope this helped. :) <3
