Answer:

EBC and CBF are supplementary.

EBD=66

Step-by-step explanation:

Since vertical angles are congruent, ABE=CBF

ABE=40-x

40-x + 6x-30=90

5x+10=90

5x=80

x=16

16(6)-30=66

5x + 9x if x =3 solve this expressioon

RSB [31]

The answer is actually 42. Not 20.

You replace each x with 3

5(3)+9(3)

That 3 right next to the five means you multiply not add.

15+27=42

Question 11 Find the value of y. X+ 13 45° No links please! Thanks for the help!

9966 [12]

Answer:

First option: $13 \sqrt{2}$

Step-by-step explanation:

$cosθ = \frac{adj}{hyp}$

$cos45° = \frac{13}{y}$

Multiply both sides by y:

$y(cos45°) = 13$

$y ( \frac{ \sqrt{2} }{2} ) = 13$

$y = 13 \div \frac{ \sqrt{2} }{2}$

$y = 13 \times \frac{2}{ \sqrt{2} }$

$y = \frac{26}{ \sqrt{2} } ( \frac{ \sqrt{2} }{ \sqrt{2} } )$

$y = \frac{26 \sqrt{2} }{2}$

$y = 13 \sqrt{2}$
