Answer: X=4

Step-by-step explanation:

Because the 90 angle is alternate exterior angle to the 21x+6. So they are equal to each other. It would be 90=21x+6. Then -6 to both sides to be 84=21x and 84/21 is 4. So X=4.

Wewaii [24]
As far as I understood, you should have attached this pic.
In this case, here are the answers 
1)  I can see there two major triads, so the answer is obviously <span>A and B.
2) When the chord is not capabable for using and does not sound properly broken we use word </span><span>Arpeggio, so the answer is B
</span><span>3) A triad is the fifth note chord, which is a set</span> of three notes. B
<span>4) </span><span>The top note of the triad is called the fifth, according to the basic rules, so the answer is C
5) </span>The interval between the root and the third of a major triad is made up of  four half steps which makes it sound smooth and holistically.
6) <span> In a major key, major triads can be built on </span><span>all above</span> scale degrees as it is the most flexible point.

Two variables have a positive linear correlation. Does the dependent variable increase or decrease as the independent variable​
andriy [413]
When two variables have a positive linear correlation, the dependent variable increases as the independent variable increases. So when the independent variable decreases, the dependent variable decreases as well. Both variables decrease and increase simultaneously.

A triangular pyramid has a base shaped like an equilateral triangle. The legs of the equilateral triangle are all 4 feet long, a
9966 [12]

Answer:

Total surface area of the pyramid =    25ft^{2}

Step-by-step explanation:

To find the surface area of the triangular- based pyramid, we will use the formula:

Surface area = Area of base + Area of the three faces

Area of base of the pyramid = Area of equilateral triangle = 0.5 \times base \times height

= 0.5 \times 4 \times 3.5= 7ft ^{2}

Area of the slant faces of the pyramid is 0.5 \times base \times slant height

0.5 \times 4 \times 3 = 6 ft^{2}

Since there are 3 slant surfaces the total surface area of the pyramid =7 + 3 \times (6)= 25ft^{2}
