HELPPPP 80 POINTS Solve the right triangle. Round your answers to the nearest tenth

Mathematics
1 answer:
aev [14]2 years ago

answer:

A=46°

a=17.983 (tenths- 18, hundredths- 17.98)

b=17.366 (tenths- 17.4, hundredths- 17.37)


explanation:

1. <u>find angle A</u>

it shows that the angle corresponding with the side length of 25 is a right angle, meaning it's 90°. using that information and the angle given to us (44°), we're able to find the missing angle. since all the angles in a triangle always add up to 180°, we can add the two angles together and then subtract that from 180° to find the missing angle.

90°+44°=134°

180°-134°=46°

A=46°

2. <u>find side a</u>

using the law of cosines, we're able to find the length of side a. cosine of an angle equals \frac{adjacent}{hypotenuse}. we'll be using angle B (44°) for our angle. after we plug in the values, we can just solve the equation to find side a.

cosine44°=\frac{a}{25}
(multiply both sides by 25)

25cosine44°=a
a=17.983

3. <u>find side b</u>

finding the length of side b is very similar to how you found side a. you can use the law of cosines again (make sure you use the right side lengths and angles!), but i used the law of sines. the sine of an angle equals \frac{opposite}{hypotenuse}. we're going to be using the same angle for this.

sine44°=\frac{b}{25}

(multiply both sides by 25)

25sine44°=b

b=17.366
