What is the value of x? Please explain the step process to getting to the conclusion.
olga55 [171]

First, split the triangle into half.

So the angle 38 becomes 38/2=19.

So we know two angles in the triangle:

One is 19 degrees.

The other one is 90 degrees (marked red).

The angles in a right-angled triangle add up to 180 degrees.

So to find the x angle, we calculate it by:

180 - (90+19) = 71

(the sum of three angles) - (the sum of the two known angles) = unknown angle

So x = 71 degrees.

Parallel to y=2/3x+6 through (-3, 6)
Lana71 [14]

Answer:

y = (2/3)x + 8

Step-by-step explanation:

Parallel lines have the same slope. In the given equation, the slope is 2/3 so the slope of the parallel line will also be 2/3.

y = (2/3)x + ?

Plug in (-3, 6) for (x, y) in the equation.

6 = (2/3)(-3) + ?

6 = -2 + ?

? = 8

Final equation: y = (2/3)x + 8

Find the number of letters from the word MAXIMUM where two consonants cannot occur. (Permutation)​
Hunter-Best [27]

Answer:

4!

Step-by-step explanation:

In word MAXIMUM, consonants are M & X. According to the question itself, consonants should not occur together.

So, we have to put vowels at each even position; only then the condition will be satisfied.

We can put this in 3! ways (permutations of A, I & U).  

For odd positions we can put 3-M's & a X. Total ways is 4!/3!   (as repetitions of M).

Hence, the answer is 4!/3! x 3! = 24 ways.  

24=4!.
