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

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

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

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

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

$\\ \sf\longmapsto c=\sqrt{89}$

$\\ \sf\longmapsto c\approx 9.22$
