1 answer:

Answer:

B. 70°

Step-by-step explanation:

If this is an equilateral triangle, then each angle is   180/3 = 60

<A = 60 = x+3x+2x

      60 = 6x

     60/6 = 6x/6

  10 =x

Angle B will also equal 60 degrees

BDA  + x + B = 180

BDA + 10 + 60 = 180

BDA + 70 = 180

BDA = 180-70

BDA = 110

BDA  and y are complementary angles since they form a straight line

BDA + y = 180

110 +y =1 80

y = 180-110

y = 70

\qquad\qquad\huge\underline{\boxed{\sf Answer}}

Things we need to keep in mind in order to plot a point :

  • x - coordinate of the point shows its distance from origin in horizontal direction.

  • y - coordinate of the point shows its distance from origin in vertical direction.

Signs of the coordinates shows which side it lies on.

  • if x coordinate is positive then the point lies on right side of y - axis and if it is negative then it lies on left side of y - axis.

similarly,

  • if y coordinate is positive then the point lies above the x - axis , and if it's negative then it lies on down the x - axis.

Now, let's proceed ~

First check out its x - coordinate on origin and move up or down according to its y - coordinate and you will get your required point.

So, for point (1 , 0) it has y - coordinate = 0, so it lies on x - axis at the x - coordinate of 1.

Answer:

-6 <= x <= 4

Step-by-step explanation:

a) -15<= 2x -3

-15+3 <= 2x

-12/2 <= x

x >= -6

b) 2x - 3 <= 5

2x <= 5 + 3

x <= 8/2

x <= 4

I WILL GIVE BRAINLIEST. HURRY PLEASE
notsponge [240]

Answer:

Concept: Linear Algebra

  1. Let us pick -5 and -4 which are one unit apart.
  2. We will find the difference by finding the slope: -3-(-11)/-4-(-5)= 8
  3. Next for 2 units apart we will choose 1 and 3
  4. We do the same thing: 53-37/3-1= 16/2=8
  5. Next we will pick something 2 units apart. Let's pick 0 and 3
  6. Hence we will do the same: 53-29/3-0= 24/3=8
  7. No matter what difference we pick, whether that be one, two or three units, the difference is the same and consistent.

When using the distance formula does the order of x and y coordinates matter? Explain.
NARA [144]

No the order does not matter because the square of a negative is positive.
