Answer: x = 11, y = 9

Step-by-step explanation:

To solve for x, set the sides equal to each other:

7x + 27 = 10x - 6

Add 6 to both sides:

7x + 33 = 10x

Subtract 7x from both sides:

33 = 3x

Divide both sides by 3:

11 = x

(Which is the same as x = 11)

Now, to solve for y, since they don’t give you the other side, you know that the straight line is 180° so:

7x + 27 + 9y - 5 = 180

Plug in your x:

7(11) + 27 + 9y - 5 = 180

77 + 27 + 9y - 5 = 180

Add like terms:

99 + 9y = 180

Subtract 99 from both sides:

9y = 81

Divide both sides by 9:

y = 9

Hope this helps!

Sin =9/15 . Find tan 0

Answer:

c. 9/12

Step by step explanation.

Given: sin = 9/15

and,

$sin = \frac{opp.}{hyp.}$

$tan = \frac{opp.}{adj.}$

thus, find adj. side

by using Pythagoras theorem

${c }^{2} = {a}^{2} + {b}^{2}$

then,

let adj. side be a^

${a}^{2} = {c}^{2} - {b }^{2} \\ {a}^{2} = {15 }^{2} - {9}^{2} \\ {a}^{2} = 144 \\ a = 12$

thus,

adj. side is 12

then,

tan of the angle = 9/12
