A = 14.9 cm, b = 14.1 cm and C = 5.7 cm for the triangle shown below.

Kaylis [27]

Answer:

X is 22.5°

Step-by-step explanation:

» Let's assume our diagram is as above, from trigonometric ratio:

${ \tt{ \red{ \sin( \theta) = \frac{opposite}{hypotenuse} }}} \\$

theta is X
opposite is a
hypotenuse is c

${ \tt{ \sin(x) = \frac{a}{c} }} \\ \\ { \tt{ \sin(x) = \frac{5.7}{14.9} }} \\ \\ { \tt{ \sin(x) = 0.3826}} \\ \\ { \tt{x = { \sin }^{ - 1}(0.3826) }} \\ \\ { \boxed{ \tt{x = 22.5 \degree}}}$

A car used 11 1/2 gal of gasoline on a 345-mile trip. How many miles can this car travel on 1 gal of gasoline? ____mi

lyudmila [28]

Answer:

The answer to your question is: 30 miles can the car travel.

Step-by-step explanation:

Data

gasoline used = 11 1/2 gal

distance = 345 mile-trip

distance travel with 1 gal = ?

Process

Convert 11 1/2 to a improper fraction 11 1/2 = 23/2

Rule of three

23/2 gal ----------------------- 345 miles

1 gal ---------------------- x

x = (1 x 345) / 23/2

x = 345 / 23/2

x = 690/ 23

x = 30 miles
