d: 30

all angles in a triangle have a sum of 180 degrees. Just add 50 and 100 (so 150) and do 180-150=30.

Use the Side-Splitter Theorem to find x given that NQ is parallel to OP.

In-s [12.5K]

Answer:

x = 7

Step-by-step explanation:

$\frac{20}{30} =\frac{14}{14+x}$

$(20)(14+x)=(30)(14)$

$280+20x=420$

$20x=420-280$

$20x=140$

$x=140/20=7$

Hope this helps

2(3x+4)=4x+12 i don’t understand please help me

Step2247 [10]

Answer:X=2

Step-by-step explanation:first you simplify the left side by multiplying the 2 with both numbers which gets you 6x+8=4x+12 then you can subtract 8 from 12 which gets you 6x=4x+4 then you subtract 4x from 6x which then gets you to 2x=4 and finally you divide the 2 from the 4 to get X alone which then gets you the answer of x= 2

Use the equation Sin (2x -9) = Cos (x+30) to solve for x. Remember that these are complementary angles!

pogonyaev

Well, if the two angles are complementary, then that means that

(2x -9)° + (x + 30)° = 90°

$\bf 3x+21=90\implies 3x=69\implies x=\cfrac{69}{3}\implies x=23$
