The length of the sides of four triangles are given. Determine which triangle is not a right triangle.a.5 mm, 12 mm, 13 mmb.20 m
gizmo_the_mogwai [7]
For a right triangle, the sum of the squares of two shorter side should be equal to the square of the third side. The calculations for each choices are shown below. 

a. (5 mm)² + (12 mm)² = 169 mm²    ;    (13 mm)² = 169 mm²   ;     EQUAL
b. (20 mm)² + (48 mm)² = 2704 mm²   ; (52 mm)² = 2704 mm²  ;    EQUAL
c. (6 mm)² + (8 mm)² = 100 mm²       ;    (10 mm)² = 100 mm²   ;     EQUAL
d. (11 mm)² + (24 mm)² = 697 mm² ;  (26 mm)² = 676 mm²  ;  NOT EQUAL

Therefore, the answer is letter D.

Solve for x. This figure is a parallelogram
stich3 [128]

Answer:

x=9

Step-by-step explanation:

Since you don't have that much information, you have to assume line HE is congruent to line GF, so now you have an equation that looks like this:  23=x+14.  Now you subtract 14 from both sides giving you 9=x, and since you cannot simplify even further, that is your answer
