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°

Answer:

The triangle is obtuse.

It is an isosceles triangle.

The angles add up to 180°.

Step-by-step explanation:

Correct statements and reasons are in bold.

The triangle is acute. No, since one angle is obtuse.

The triangle is obtuse.  Yes, because it has an obtuse angle.

It is an isosceles triangle.  Yes, because 2 sides are congruent.

It is a scalene triangle.  No, since 2 sides are congruent.

It is an equilateral triangle.  No, since not all sides are congruent.

The angles add up to 180°. Yes because that is true for every triangle.

Can u help with these two
Artemon [7]
The volume of a rectangular prism can be given by the form
V= b*h*w

you know Volume, base, and height but you dont know width

so divide b and h to both sides
\frac{V}{b*h} = w
and you cna solve for width

now for 6.
dividing by a number is the same as multiplying by its reciprocal

n \div 6  = n * \frac{1}{6}

What is the value of tan A?
Ronch [10]

For the given triangle, the tan of angle A equals \frac{3}{4} = 0.75.

Step-by-step explanation:

Step 1:

In the given triangle for angle A, the opposite side has a length of 6 cm, the adjacent side has a length of 8 cm while the hypotenuse of the triangle measures 10 cm. To calculate the tan of angle A we divide the opposite side's length by the adjacent side's length.

tan A = \frac{oppositeside}{adjacent side}.

Step 2:

The opposite side's length = 6 cm.

The adjacent side's length = 8 cm.

tan A = \frac{oppositeside}{adjacent side} = \frac{6}{8} = \frac{3}{4} = 0.75.
