Set up the trig equation with the correct values plugged in that you would use to solve for h. (You do not need to solve)

From the reference of the 18 degree angle, 'h' is the opposite side and 100 is the adjacent side.

The trig ratio which uses both the opposite and adjacent sides is the tangent.

tan(18) = opp/adj = h/100

Trig equation:
tan(18) = h/100

Help, I’m stuck. Lol.
Darya [45]

Answer:

a. height = 12

b. area = 228

Step-by-step explanation:

a. To find the height, we can use the triangle formed by the side that measures 15, the side that measures 9. and the height. The hypotenuse of the triangle(the longest side opposite of the right angle), is 15. We can then use the Pythagorean Theorem, which states that a^2+b^2=c^2, where c is the hypotenuse, and a and b are the two other sides. In this case, we need to find a leg of the triangle, not the hypotenuse. What do we do? We can first call the height a, and rearrange the Theorem into c^2-b^2=a^2. 15^2=225, 9^2=81, and 225-81=\sqrt{144}=12. Therefore, the height of the parallelogram is \boxed{12}

b. To find the area of the parallelogram, we can use the area formula, which is Base*Height. The base is the flat side. We can find the base by adding 9+10=19, and 19\cdot12=\boxed{228}

What is the value of x- This is for brainliest!
aleksandr82 [10.1K]
You would need to write a solvable equation, and you can do this because you know that angles in a triangle add up 180° so the missing angle must be (180 - 9x). This makes the equation:
5x + 9 + x + (180 - 9x) = 180
6x + 9 + 180 - 9x = 180
-3x + 189 = 180
- 189
-3x = -9
÷ -3
x = 3

So your answer is x = 3, I hope this helps!

If I flip a coin 56 times how many times will it land on heads I’d the probability is 1/2 or 50 present
aliya0001 [1]

Answer:

28

Step-by-step explanation:

So its a 50/50 chance for the coin to land on heads or tails, so we would divide 56 by 2

56/2 = 28
