RS+ST= RT
(7Y+3)+(2Y+9)= 14Y-8
9Y+12=14Y-8
5Y=20
Y=4

Solve for x in the triangle.Round your answer to the nearest tenth.

enyata [817]

sin = opposite/hypotenuse

sin 40° = 12/x

Cross multiply.

0.64278760968x = 12

Divide both sides by sin 40°.

x = 18.7 (rounded to nearest tenth).

Answer:

Option (A).

Step-by-step explanation:

$8\frac{4}{5}$ is a mixed fraction and can be written as,

$8\frac{4}{5}=8+\frac{4}{5}$ [Combination of a whole number and a fraction]

When we multiply this mixed fraction by 7,

$7\times 8\frac{4}{5}=7\times (8+\frac{4}{5})$

$=(7\times 8)+(7\times \frac{4}{5})$ [Distributive property → a(b + c) = a×b + a×c]

$=56+\frac{28}{5}$

$=56+5\frac{3}{5}$

$=56+5+\frac{3}{5}$

$=61+\frac{3}{5}$

$=61\frac{3}{5}$

Therefore, $7\times 8\frac{4}{5}=61\frac{3}{5}$ will be the answer.

Option (A) will be the correct option.
