Find the measurement parallelogram.<br> I need help please, thank you.<br> I need explanation
blondinia [14]

Answer:

2.) 145°

4.) 50°

Step-by-step explanation:

2.) First find the measure of Angle Y, since they are supplementary;

∠Z + ∠Y = 180

35 + ∠Y = 180

∠Y = 180 - 35

∠Y = 145°

So ∠X would be 145° as well

4.) First find the measure of Angle F, since they are supplementary;

∠C + ∠F = 180

130 + ∠F  = 180

∠F = 180 -130

∠F = 50°

So ∠E would be 50°

(I didn't explain it much in detail, since this question is similar to the previous that i answered :)

Hope this helps!

Please help need help bad
Shkiper50 [21]
Hello! The first thing you want to do is add 4 to both sides, which gives you: 7over9x - 4 + 4 = 24 + 4. Then Simplify: 7over9x = 28. Then you just multiply both sides by the number 9! 9 times 7over9 = 28 times 9. Simplfy again! 7xover7 = 252over7. Simply that fraction, and you get x=36. 

~I hope this helped!

I am, yours most sincerely,

Determine the exact value of sin 13pi/12
ohaa [14]
To answer the problem above, convert the given angle to an equivalent angle with the unit of degrees.
                               (13π / 12 rad) x (360° / 2π) = 195°
We can solve this by directly inputting the value in our scientific calculators. The answer is approximately -0.2588.
