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

Margaret [11]

Answer:

Chart 2.

Step-by-step explanation:

In the figure Dan has constructed an angle at point Q.He wants to cinstruct an angle ar point R which is congruent to angle made at point Q.To construct the angle at point R Dan needs to draw an arc at point R .He will put the compass on point R and draw an arc .This is shown in the figure 2.

The figure is added below.
