Answer:
Step-by-step explanation:
Hello There!
We can find y by using trigonometric ratios
sine, cosine and tangent
the opposite of the angle that has a measure of 28 degrees is y and the side that is adjacent to the angle is 35
so...
now we solve for y using basic algebra
we want to isolate the variable (y) using inverse operations
to get rid of the 35 we multiply each side by 35
now we let the calculator do the rest of the work
*round to the nearest thousandth*
we're left with
y = 18.610
hence your answer is B

Answer:
x = 9 and ∠ JKM = 59°.
Step-by-step explanation:
See the attached diagram with this question.
∠ JKL is bisected by line KM.
Therefore, angle JKM = angle MKL
Now, ∠ JKM is given to be ( x² - 22 ) and ∠ LKM = ( 6x + 5 ).
So, x² - 22 = 6x + 5
⇒ x² - 6x -27 = 0
⇒ ( x - 9 ) ( x + 3 ) = 0
Therefore, x = 9 or - 3.
∠ JKM = x² - 22 = 59° for x = 9 and ∠ JKM = x² - 22 = - 13° for x = - 3
Since angle JKM can not be negative, so, x = 9 and ∠ JKM = 59°. (Answer)
180 ÷ 45 is 4
so
4 time 20 is 80
