-183c +210

you have to distribute 1 to the parenthesis and then do the same with 13.

after you do that combine the like terms.

Answer:

$\boxed{\boxed{\sf x=42\°}}$

Step-by-step explanation:

Given the diagram, we can see that ∠PQR and ∠RQS are complementary angles.

*Two angles with measures that add up to 90° are known as Complementary angles.*

Therefore, m∠PQR+m∠RQS=90°

$\sf \angle PQR+\angle RQS=90\°$

$\sf 48+x=90\°$

Subtract 48 from both sides:

$\sf 48+x-48=90-48$

$\sf x=42\°$

The answer to number 3

Reptile [31]

Answer:

4.5×10^17 m²

Step-by-step explanation:

The radius is half the diameter, so we can make the substitution r=d/2 into the formula to get ...

A = 4πr² = 4π(d/2)² = πd²

Filling in the given values and doing the arithmetic gives ...

A = 3.14×(3.8×10^8 m)² = 45.3416×10^16 m²

A ≈ 4.5×10^17 m²

We round to 2 significant digits because that is the precision of the given diameter.
