Answer:
Yes, the sides form a right triangle.
Step-by-step explanation:
<u>Pythagorean Theorem:</u>
a² + b² = c²
↓
20² + 21² = 29²
║a² = 20² = 400
║b² = 21² = 441
║c² = 29² = 841
↓
400 + 441 = 841
║This equation is true.
↓
Yes, the sides form a right triangle.
Answer:
<h3><em>g(x)=3x-1=7</em></h3><h3><em><=> 3x=8</em></h3><h3><em><=> x=8/3</em></h3>
So,
a parallelogram is forming here
then, opposite angels are going to be equal
so,
y = (x+50)°
now,
as you know that sum of all angles of a quadrulateral equals 360°
so,
2 {(x+50)+(x-30)}=360°
(x+50)+(x-30) = 180°
2x + 20 = 180
2x = 160
x = 80°
therefore,
angle y = (x+50) = 80 +50 = 130°
and x = (x-30) = 80 - 30 = 50°
Answer:
The answer would be B.
Step-by-step explanation:
Because both the triangles have different sides and they don't follow SAS or SSS criterion.
