If x is 32 mm what’s the area of the triangle
Ksju [112]

Answer:

4608*sqrt(3)

Step-by-step explanation:

x + 2x = 3x, so 3x is the height of the triangle.  This is a 90-60-30 triangle so the base would be 3x*sqrt(3).  To find the area, we can multiply the base with the height and divide by two, so it would be (3x)(3x*sqrt(3))/2 or (9/2)x^2 * sqrt(3).  x = 32, and plugging this into the equation gets us to (9/2)32^2 * sqrt(3), which is 4608*sqrt(3).

If Janet scored an 85% on her test she answered 34 questions correctly how many questions were on the test
Wittaler [7]
40 questions. You set up a proportion, mutiply 34 by a 100 and get 3400. Then you divide 3400 by 85 and you get ur answer. You could also try guessing by putting in random values you think are the whole number and multiplying them by 0.85. So if you guess 44 is the whole and try checking it by multiplying it by .85 and get a value thats higher than the value the percentage is equal to you try another smaller value. So if 44 doesn't work you can try 40. 40 times .85 is 34 so your answer of 40 questions is correct.

What’s the correct answer for this?
dybincka [34]

Answer:

(A)

Step-by-step explanation:

Using the formula :

Area = 1/2 [-1(1 - 6) -7(6 - 1) -3(1 - 1)]

Area = 1/2 [5 - 35]

Area = 1/2 × -30 = |-15| = 15 units²
