B
00
A
15
с
A. 17
B. 60
C. 17
D. 289

Answer 1

• Perpendicular=P=8
• Base=B=15
• Hypotenuse=H

Using Pythagorean Theorem

`\\ \sf\longmapsto H^2=P^2+B^2`

`\\ \sf\longmapsto H^2=8^2+15^2`

`\\ \sf\longmapsto H^2=64+225`

`\\ \sf\longmapsto H^2=289`

`\\ \sf\longmapsto H=√(289)`

`\\ \sf\longmapsto H=17`

• BC=17
