Question

Find C to two decimal places and find the measurement of angle be use your calculator

Answer 1

Let's solve

• P=8
• B=5

Using Pythagorean theorem

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

`\\ \sf\longmapsto c^2=8^2+5^2`

`\\ \sf\longmapsto c^2=64+25`

`\\ \sf\longmapsto c^2=89`

`\\ \sf\longmapsto c=√(89)`

`\\ \sf\longmapsto c\approx 9.22`
