The right triangle has an angle of 30°-60°-90°
8 + 7 is 15 so if we round 15 to the nearest tenth what is it
121 = 112 - k • -3
9 = k • -3
k = -3
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.
