An isosceles triangle has legs with length 10 units. Which of the following could be the perimeter of the triangle? Choose all that apply. Explain your reasoning. A 22
B 20
C 32
D 39
E 40

By the Triangle Inequality Theorem, the range of possible lengths of the third side is 0 < x <
.
So, the perimeter for all possible triangles must be greater than
units and less than
units.

What is the difference between the predicted value and the actual value

Statement reason 1. δabc is similar to δced. given 2. 3. definition of slope 4. slope of slope of definition of slope 5. slope of × slope of multiplying the slopes 6. slope of × slope of substitution property of equality 7. slope of × slope of simplifying the right side the table contains the proof of the relationship between the slopes of two perpendicular lines. what is the reason for statement 2? a. parallel line segments that meet a common perpendicular line are proportional in length. b. the lengths of vertical and horizontal sides in congruent triangles are in a common ratio. c. trigonometric identities determine the lengths of the legs in a right triangle. d. corresponding side lengths in similar triangles are proportional in length.

How do i i solve this equation? -18 = x/3 + 3
