Answer 2

Step-by-step explanation:

Question: 1

$\bold{4\sqrt{5}+5\sqrt{5}= ? }$

Answer:

$\bold{4\sqrt{5}+5\sqrt{5} }$

Taking $\bold{\sqrt{5} }$ common:

$\bold{4+5\sqrt{5} }$

$\bold{9\sqrt{5} }$

∴ Right option is d) $\bold{9\sqrt{5} }$.

Question: 2

Find the value of k if p║q.

Answer:

We have, two angle's measures :

• (45 - k)°
• (k)°

We know,

Alternate exterior angles are formed when a transversal passes through two lines and these angles are equal and they are also equal to 180°.

That is,

⇒ (45 - k)° = (k)°

⇒ 45 - k - k = 180°

⇒ 45 - 2k = 180°

⇒ -135° = -2k

⇒ k = 67.5°

∴ Value of k is 67.5°.
