Answer:

AC ≈ 16.8 cm ( to 1 dec. place )

Step-by-step explanation:

Using the sine ratio in the right triangle

sin71° = \frac{opposite}{hypotenuse} = \frac{AB}{AC} = \frac{15.9}{AC}

Multiply both sides by AC

AC × sin71° = 15.9 ( divide both sides by sin71° )

AC = \frac{15.9}{sin71} ≈ 16.8 cm

Answer:

16.8 cm

Step-by-step explanation:

Sin (theta)=opposite/HYPOTENUSE

Where theta=71 and opposite=15.9

Putting in the above formula

Sin 71=15.9/AC

AC=15.9/sin71

AC=15.9/0.945

AC=16.8 cm

Can anyone solve this for me????
sweet-ann [11.9K]

The old rate of pay is x and the new rate is y then we have:

y = 2x + 7

Y = 21

PART 1:  21 = 2x+7

Subtract 7 from each side:

14 = 2x

Divide both sides by 2:

X = 14 / 2

X = 7

PART 2: The internship pays $7 per hour.

2x  -  48  =  10x

-2x                -2x

-48  =   8x

/8          /8

-6   =  x

if you move all of your x's on to the same side it is easier to solve

This is part 1. Please help
ahrayia [7]
For the first one you would do:
X rad 3=7 divide by rad 3 in both sides and you don’t wanna leave a radical in the denominator so multiply rad 3 in both denom. And numerator and then you get 7rad3/3.

A 30:60:90 triangle always have n:2n:n rad 3 so since 2n=10 you would get n=5 and since BC is n rad3 so you would get 5rad 3.

In a 45:45:90 triangle it is n:n:n rad 2, since AC=3 then AB= 3 and then BC= 3 rad 2

Since AC and AB are congruent you they both would be 12 so it is true.
