Which statements are true about the triangle? Select all that apply.

Bogdan [553]

Answer:

The triangle is obtuse.

It is an isosceles triangle.

The angles add up to 180°.

Step-by-step explanation:

Obtuse triangles are defined as triangles with one angle obtuse angle over 90°. This triangle has an angle of 100°, so it is an obtuse triangle!

Isosceles triangles have 2 equal sides. The two orange dashes on the left and right legs of the triangle tell us they are equivalent, so this is an isosceles triangle as well!

Finally, <em>all </em>triangles add up to 180°! We can prove this by adding the angles.

40° + 40° = 80°

100° + 80° = 180°

Jaime has 5 over 11 spaceof a project completed while Tim has finished 7 over 13 spaceof the same project.

lina2011 [118]

Tim has completed greater amount of work and overall they have completed 142/143 of the project work

Step-by-step explanation:

Given

Work completed by Jaime = j = 5/11

Work completed by Tim = t = 7/13

<u>a. Who has completed the greater amount of work?</u>

In order to see that we have to convert the fractions in decimal

So,

j = 5/11 = 0.45

t = 7/13 = 0.53

As we can see that the decimal for Tim's work space is large, Tim has completed greater amount of work

b. How much of the project have they completed together? Show your work.

We have to find the total work done by them

$Total\ work = j + t\\= \frac{5}{11} + \frac{7}{13}\\=\frac{65+77}{143}\\=\frac{142}{143}$

Hence,

Tim has completed greater amount of work and overall they have completed 142/143 of the project work
