Answer:

The sum of the interior angles of a triangle is 180 degrees.

d. Scalene

e. Isosceles

f. Isosceles

g. Equilateral

h. Scalene

i. Equilateral

j. Right

l. Acute

m. Obtuse - doesn't add to 180 not a triangle

n. Acute - doesn't add to 180 not a triangle

o. Obtuse

Step-by-step explanation:

The interior angles of a triangle add to 180 degrees. There are two ways we classify triangle by side lengths and angle measures.

Side lengths: Compare the side lengths and see if any are equal to determine the type.

Scalene: 3 different lengths
Isosceles: 2 equal lengths and 1 different
Equilateral : 3 equal sides

Angle Measures: Compare the angles measures to 90 degrees.

Right: If one angle is equal to 90
Acute: All angles are less than 90 degrees
Obtuse: One angle is greater than 90 degrees

15 + (5-x)/x=30 solve for x

elixir [45]

Answer:

5/16

Step-by-step explanation:

15+(5-x)/x=30

1) Subtract 15 from both sides:

(5-x)/x=15

2) Multiply both sides by x:

5-x=15x

3) Add x to both sides:

16x=5

4) Divide both sides by 16:

x=5/16

Fudgin [204]

x + 47 = 92. <--- x represents the number of 3rd graders

x +47-47 = 92-47

x=45

There are 45 third grader. Hope this helped!
