Answer:
Refer to step-by-step.
Explanation:
1. x = 4
x + 3 = 7
x = 7-3
x = 4
2. x = 25
We need to use the Pythagorean theorem to find x.
a² + b² = c²
15² + 20² = x²
225 + 400 = x²
652 = x²
√652 = √x²
x = 25
3. x = 12
Line NP and Line QP will have the same measurement.
x = 12
4. x = 29.41
We need to use the Pythagorean theorem to find x.
a² + b² = c²
24² + 17² = x²
576 + 289 = x²
865 = x²
√865 = √x²
x = 29.41
5. NO
We apply the Pythagorean theorem to find if they are tangent.
a² + b² = c²
9² + 40² = 41²
81 + 1600 = 2500
1681 = 2500 NO
6. NO
a² + b² = c²
4² + 12² = 13²
16 + 144 = 169
160 = 169 NO
7. NO
a² + b² = c²
20² + 21² = 28²
400 + 441 = 784
841 = 784 NO
8. YES
a² + b² = c²
14² + 48² = 50²
196 + 2304 = 2500
2500 = 2500 YES
