Answer:
No
Step-by-step explanation:
The only arithmetic sequence of side lengths that will form a right triangle is (3, 4, 5) or some multiple of that, such as (9, 12, 15).
Sides of length 10, 11, 12 cannot form a right triangle.
Answer:
the distance is 8
Step-by-step explanation:
Answer:
40°, 60° and 80°
Step-by-step explanation:
sum the parts of the ratio, 2 + 3 + 4 = 9 parts
Divide 180° ( sum of angles in a triangle) by 9 to find the value of one part of the ratio.
180° ÷ 9 = 20° ← value of 1 part of the ratio , then
2 parts = 2 × 20° = 40°
3 parts = 3 × 20° = 60°
4 parts = 4 × 20° = 80°
The angles in the triangle are 40°, 60°, 80°
Answer:
45 is the range.
Step-by-step explanation:
The range is the difference between the highest value and the lowest value.
464 - 419 = 45
Answer:
(20+2)(20-2) = 20^2 - 2^ = 396
Step-by-step explanation:
Difference of two squares is breaking down numbers into pieces and using the distributive property to solve. The pieces should be in the form (a-b)(c+d).
Write 22 as (20 + 2) and 18 as (20-2).
(20+2)(20-2) = 400 + 40 - 40 - 4 = 400 - 4 = 20^2 - 2^ = 396
