Answer:

Step-by-step explanation:

If they were joined together, wouldn't the length of both squares combined be 20cm?

Therefore, it'd be (10+20+10+20) for the perimeter.

60cm.

Answer:

\sf Since \;\sqrt{\boxed{64}}=\boxed{8}\;and\;\sqrt{\boxed{81}}=\boxed{9}\; \textsf{it is known that $\sqrt{75}$ is between}\\\\\sf \boxed{8}\;and\;\boxed{9}\;.

Step-by-step explanation:

<u>Perfect squares</u>: 4, 9, 16, 25, 36, 49, 64, 81, 100, 121, ...

To find \sf \sqrt{75} , identify the perfect squares immediately <u>before</u> and <u>after</u> 75:

  • 64 and 81

\begin{aligned}\sf As\;\; 64 < 75 < 81\; & \implies \sf \sqrt{64} < \sqrt{75} < \sqrt{81}\\&\implies \sf \;\;\;\;\;8 < \sqrt{75} < 9 \end{aligned}

\sf Since \;\sqrt{\boxed{64}}=\boxed{8}\;and\;\sqrt{\boxed{81}}=\boxed{9}\; \textsf{it is known that $\sqrt{75}$ is between}\\\\\sf \boxed{8}\;and\;\boxed{9}\;.

See the attachment for the correct placement of \sf \sqrt{75} on the number line.

g100num [7]

Answer:42.98

Step-by-step explanation:

Hf=√(11^2-8^2)

Hf=√(121-64)

Hf=√(57)

Hf=7.5

11/sin90 =7.5/sinG

Sin90=1

11/1=7.5/sinG

Cross multiply

11 x sinG=7.5 x 1

11sinG=7.5

Divide both sides by 11

11sinG/11=7.5/11

sinG=0.6818

G=sin(inverse)(0.6818)

G=42.98
