I REALLY NEED HELP PLEASE

Mathematics
1 answer:

Answer:

sin X =  12/13

cos X = 5/13

tan X = 12/5

Step-by-step explanation:

Recall the definitions as follows:

For a right triangle (i.e one angle is 90 deg) with one of the angles X

sin X = opposite side / hypotenuse

cos X = adjacent side / hypotenuse

tan X = opposite side / adjacent side

In our case for angle A, the following applies:

opposite = 36

adjacent = 15

hypotenuse = 39

hence

sin X = opposite side / hypotenuse = 36/39 = 12/13

cos X = adjacent side / hypotenuse = 15/39 = 5/13

tan X = opposite side / adjacent side = 36 /15 = 12/5

In the diagram, JOK and MON are straight lines. Angle NOP and Angle NOQ are complimentary angles. Calculate the value of x - y.
Pepsi [2]

Answer:

x - y = 118

Step-by-step explanation:

Since ∠ NOP and ∠ NOQ are complimentary then ∠ POQ = 90°

Since JOK is a straight line then

∠ JOP + ∠ POQ + ∠ QOK = 180 , that is

76 + 90 + y = 180

166 + y = 180 ( subtract 166 from both sides )

y = 14

Since MON is a straight line then

∠ MOK + ∠ KOQ + ∠ QON = 180, that is

x + 14 + 34 = 180

x + 48 = 180 ( subtract 48 from both sides )

x = 132

Thus

x - y = 132 - 14 = 118

How can you tell it if linear or non-linear​
Snowcat [4.5K]
In linear equations, the graph will always be a straight line. In non linear equations, the graph may look like a parabola (curvy instead of straight).

Plz help me with dis its one question
tatiyna

Answer:

Alix does. See below.

Step-by-step explanation:

Givens

<em><u>Jenny</u></em>

  • b1 = 90 cm
  • b2 = 80 cm
  • height = 23 cm

<em><u>Alex</u></em>

  • b1 = 90 cm
  • b2 = 70 cm
  • height = 27 cm

Formula

For both territories the answer is based on the formula

  • Area = (b1 + b2)*h/2

Solution

<em><u>Jenny</u></em>

  • Area = (90 + 80)23/2
  • Area = 170 * 23 / 2
  • Area = 85 * 23
  • Area = 1955 units.

<em><u>Alex</u></em>

  • Area = (70 + 90)*27/2
  • Area = 160*27 / 2
  • Area = 80* 27
  • Area = 2160

Which graph best represents the equation 2x + 4y equals negative 8
Hitman42 [59]
You have to solve for y
Subtract 2x to the other side
Divide both sides by 4
y=-1x/2-2
Graph D has a slope of -1/2 and a y-intercept of -2
