The lengths of 3 sides of a triangle are given. Use the Pythagorean Theorem (a? + b2 = c?) to determine if the triangle is a right triangle. (Show your work.)
1. a = 9 in, b = 12 in, c = 15 in
2. a = 8 cm, b = 15 cm, c = 17 cm
3. a = 3 m, b = 2 m, c = 13 m
Yes, it's a right triangle.
No, it's not a right triangle.
Yes, it's a right triangle.
No, it's not a right triangle.
Yes, it's a right triangle.
No, it's not a right triangle.
4. a = 2 ft, b= 1 ft, c=v5 ft
5. a = 5 m b = V11 m, c = 6 m
6. a = 2 m b = 6 m, c = 20 m

No, it's not a right triangle.

step-by-step explanation:

y = | -2(-2) |     →     y = | 4 |     →     y = 4       ⇒   (-2, 4)

y = | -2(-1) |     →     y = | 2 |     →       y =   2       ⇒   (-1, 2)    

y = | -2(0) |     →     y = | 0 |     →       y = 0         ⇒   (0, 0)

y = | -2(1) |   c →     y = | -2 |     →     y =   2         ⇒   (1, 2)    

y = | -2(2) |     →     y = | - 4 |     →     y =   4         ⇒   (2, 4)  

answer: (c) m∠qpo + (2x + 16)° = 180°

step-by-step explanation:

the opposite angles of a quadrilateral are supplementary.

so, ∠o + ∠q = 180°   and   ∠p + ∠r = 180°

since ∠r = 2x + 16°, we can use substitution as follows:

∠p + ∠r = 180°

∠p + (2x + 16)° = 180°

c

step-by-step explanation:

the multiples of 15 are 15, 30,45, 60, 75, 90, 105, 120, 135, 150, 165, 180, 195,   210, 225, 240, 255, 270, 285, 300, 315, 330, 345, 360, 375,   390, 405, 420, 435, 450, 465, 480, 495, 510, 525, 540, 555, 570, 585, 600, 615, 630, 645, 660, 675, 690, 705, 720, and 735.

the factors of 15 are 1, 3, 5, and 15.

hope that , fam!
