Answer: 4 mm

Step-by-step explanation: this is because if you double the area then you will get the Area of 80 and if you divide it by 20 you will get 4 mm

Use the formula for area of a triangle:

Area = 1/2 x base x height.

Fill in what you know:

40 = 1/2 x 20 x height

Multiply both sides by 2:

80 = 20 x height

Divide both sides by 20

Height = 4 m

Given that tan θ ≈ 1.072, where 0 &lt; θ &lt; , 2 π find the values of sin θ and cos θ.
anygoal [31]

Answer:

The answer to your question is

sin Ф = 0.731 and sinФ = -0.731; cos Ф 0.682 and cos Ф = -0.682

Step-by-step explanation:

tan Ф = 1.072,  0 < Ф < 2 π,   tan Ф is positive, find the solution in the first and third quadrangle.

- tan Ф = opposite side / adjacent side

- 1.072 / 1 = opposite side / adjacent side

- opposite side = 1.072 and adjacent side = 1

  Calculate hypotenuse

  c² = a² + b²

  c² = 1.072² + 1²

  c² = 2.149

  hypotenuse = c = 1.466

First quadrangle

  sin Ф = 1.072 / 1.466 = 0.731

  cos Ф = 1 / 1.466 = 0.682

Third quadrangle

  sin Ф = -1.072 / 1.466 = -0.731

  cos Ф = -1 / 1.466 = -0.682

Decide which of the two points lies on the graph of the line<br> X= -3 <br> A. 2,-3 <br> B. -3,2
rusak2 [61]
Umm, since x is -3 (given), your answer should be B, since B is the only one with -3 as an x

hope this helps

How do you solve -2/3x + 5 = 20 - x
Monica [59]

-2/3x + 5 = 20 - x

subtract 5 from each side

-2/3 x = 15 -x

add x to each side

-2/3 x +x = 15

get a common denominator of 3 for the x terms

-2/3x + 3/3 x =15

combine like terms

1/3 x = 15

multiply by 3 on each side

x = 45

Answer: x=45
