Find the value of h in the parallelogram. Round your answer to the nearest tenth​
Free_Kalibri [48]

Answer:

h=7.5 in

Step-by-step explanation:

see the attached figure with letters to better understand the problem

In the right triangle ABC

sin(CAB)=15/18 ----> opposite side divided by the hypotenuse

In the right triangle CDE

sin(DCE)=h/9 ----> opposite side divided by the hypotenuse

In this problem

∠CAB=∠DCE ------> by corresponding angles

therefore

sin(CAB)=sin(DCE)

15/18=h/9

solve for h

h=15*9/18

h=7.5 in

PLEASE HELP ME!!!!<br><br> (if you don’t know don’t answer)
Sergio039 [100]

Answer:

Here are my answers

hope this helps

Step-by-step explanation:

1. isosceles triangle

2.   3x + 15 = 90       x = 25

     x + 25 = 90        x = 65

     x + 55 = 90        x = 35

3. The size for DAB is 84

My reasoning is I went from one angle to another by subtracting 180 from my answers. For example angle 132 is supplementary to the missing angle next to it. I subtract 180 from 132 and get 48. That already solves the 2 equivalent angles in the triangle so I have 48+48+x = 180 because a full triangle equals 180. I get x = 84 then I do the same thing I did with angle 132. Angle 84 is supplementary to the missing angle next to it. I subtract 84 from 180 and get 96 then go diagonal from angle C (which is 96) to angle A. Those are supplementary so I subtract 96 from 180 and get 84.

40% of 400- how to solve please (thanks
Alexxandr [17]

Step-by-step explanation:

What is 40% of 400?

  • Convert the problem to an equation using the percentage formula: P% * X = Y
  • P is 40%, X is 400, so the equation is 40% * 400 = Y
  • Convert 40% to a decimal by removing the percent sign and dividing by 100:40/100 = 0.4
  • Substitute 0.10 for 10% in the equation: 40% * 400 = Y becomes 0.4 * 400 = Y
  • Do the math: 0.4 * 400 = 160
  • Y = 160
  • So 10% of 150 is 160
  • Double check your answer with the original question: What is 40% of 400? Multiply 0.4 * 400 = 160
