Answer:

x = -15 thus c: is your answer

Step-by-step explanation:

Solve for x:

10 = (-2 x)/3

10 = (-2 x)/3 is equivalent to (-2 x)/3 = 10:

(-2 x)/3 = 10

Multiply both sides of (-2 x)/3 = 10 by -3/2:

(-3 (-2) x)/(2×3) = (-3)/2×10

(-3)/2×(-2)/3 = (-3 (-2))/(2×3):

(-3 (-2))/(2×3) x = (-3)/2×10

(-3)/2×10 = (-3×10)/2:

(-3 (-2) x)/(2×3) = (-3×10)/2

(-3)/3 = (3 (-1))/3 = -1:

(-2-1 x)/2 = (-3×10)/2

(-2)/2 = (2 (-1))/2 = -1:

--1 x = (-3×10)/2

(-1)^2 = 1:

x = (-3×10)/2

10/2 = (2×5)/2 = 5:

x = -35

-3×5 = -15:

Answer:  x = -15

Solving a right triangle (ROUND TO THE NEAREST TENTH)
Kay [80]

Answer:

see explanation

Step-by-step explanation:

The sum of the 3 angles in a triangle = 180°

Subtract the sum of the given angles from 180 for B

B = 180° - (90 + 40)° = 180° - 130° = 150°

--------------------------------------------------------------

sin40° = \frac{opposite}{hypotenuse} = \frac{a}{21}

Multiply both sides by 21

21 × sin40° = a, thus

a ≈ 13.5 ( to the nearest tenth )

--------------------------------------------------------------

cos40° = \frac{adjacent}{hypotenuse} = \frac{b}{21}

Multiply both sides by 21

21 × cos40° = b, thus

b ≈ 16.1 ( to the nearest tenth )

Can someone help me find x please
a_sh-v [17]

Answer:

38.7°

Step-by-step explanation:

We can solve the triangle using the trigonometrical ratios which may be expressed in the form SOA CAH TOA Where

SOA stands for

Sin Ф = opposite side/hypotenuses side

CAH stands for

Cosine Ф = adjacent side/hypotenuses side

TOA stands for

Tangent Ф = opposite side/adjacent side

The hypotenuse is the side facing the right angle while the opposite is the side facing the given angle.

Considering the triangle with respect to angle x, 8cm is the opposite side, 10cm is the adjacent side

hence

Tan x = 8/10

Tan x = 0.8

x = tan -1 0.8

= 38.7°
