Answer:

1. 90      2. 130       3. 55

Step-by-step explanation:

Every triangle when you add all the angles will = 180 degrees for this you add the 2 angles that you have and subtract it from 180

1.   35+55+ C = 180

90 = 180

C = 90

2. 25+25+C = 180

50 + C = 180

C = 130

3. 62 + 63 + C = 180

125 + C = 180

C = 55

Answer:

Step-by-step explanation:

sum of all the angles of triangle = 180

1) ∠1 + ∠2 + ∠3 = 180

35 + 55 + ∠3 = 180

90 + ∠3 = 180

       ∠3 = 180 -90

            ∠3 = 90

If one angle is 90, then, it is a right angled triangle.

2) 25 + 25+ ∠3 =180

        50 + ∠3 =180

             ∠3 =180 -50

       ∠3 = 130

If two angles are equal, then it is an isosceles triangle.

3) 62 + 63 + ∠3 =180

             125 +∠3=180

                     ∠3 = 180-125

                     ∠3 = 55

All the angles are different, so it is a scalene triangle

The value of  sin (90° - 9) is 11/15, Option A is correct.

Trigonometry is a branch of mathematics that studies relationships between side lengths and angles of triangles.

Using the trigonometric identity sin(90° - θ) = cos(θ), we have:

sin(90° - 9) = cos(9)

To evaluate cos(9) in degrees,

cos(θ) = cos(π/2 - θ)

Substituting θ = 9 degrees, we get:

cos(9) = cos(π/2 - 9°)

Using radians, π/2 - 9° = 1.4661

cos(9) = 0.9781

Therefore, sin(90° - 9) = 0.9781, which is equivalent to 11/15 when simplified.

[tex]\huge \colorbox{blue}{B}[/tex]

Step-by-step explanation:

we are given the formula,Mass and volume

to find density we just need to substitute the value of mass and value and simplify it

[tex] \sf substitute \: the \: value \: of \: mass \: and \: volume : [/tex]

[tex] \quad \: \sf \dfrac{7.0 \times {10}^{24} \: kg }{3.5 \times {10}^{12} \: {km}^{3} } [/tex]

now we will use [tex]\dfrac{x^m}{x^n}=x^{m-n}[/tex] to simplify division

Step-by-step explanation:

Hello, I am no math expert so take this with a grain of salt. Tan=Opposite/Adjacent. Side ON is opposite and side MN is Adjacent. This would mean that the ration would be 5/12. I hope that helped!

Answer:

Since 5 is in most of the answers, I´m guessing that 5 is the length of the short leg. The answer is C

Step-by-step explanation:

In SohCahToa, Sine, Cos, and Tan all have a formula. Since your looking for tan, you would find the sides that are opposite and adjacent to the hypotenuse. And since tan is opposite over adjacent, it would be 5 over 12.

Sine=Opposite over Hypotenuse

Cos=Adjacent over Hypotenuse

Tan=Opposite over Adjacent

Answer:

15a² + 21a + 19 = 0

Step-by-step explanation:

Given

(4a + 3)² = (a + 5)(a - 2)

(4a + 3)(4a + 3) = (a + 5)(a - 2 ) ← expand both sides using FOIL

16a² + 24a + 9 = a² + 3a - 10 ( subtract a² + 3a - 10 from both sides )

16a² - a² + 24a - 3a + 9 + 10 = 0 ← collect like terms

15a² + 21a + 19 = 0
