Solving the right triangle ‼️ (Round to the nearest tenth) can someone help me find A,a, and b❓

Answer:

see explanation

Step-by-step explanation:

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

Subtract the sum of the 2 angles from 180 for A

A = 180° - (50 + 90)° = 180° - 140° = 40°

Use the cosine and sine ratios in the right triangle for a and b

cos50° = \frac{adjacent}{hypotenuse} = \frac{a}{26}

Multiply both sides by 26

26 × cos50° = a, thus

a ≈ 16.7 ( to the nearest tenth )

sin50° = \frac{opposite}{hypotenuse} = \frac{b}{26}

Multiply both sides by 26

26 × sin50° = b, thus

b ≈ 19.9 ( to the nearest tenth )

The difference between a number b and 7.4 is -6.8
Lera25 [3.4K]

Hello from MrBillDoesMath!

Answer:

b = 0.6


Discussion:

The question can be written as

b - 7.4 = -6.8  =>           (now add 7.4 to each side)

b - 7.4 + 7.4 = -6.8 + 7.4 =>       ( note: -7.4 + 7.4 = 0)

b = 0.6

Thank you,

MrB

Huw has a maths test. the second question is:
xeze [42]

Huw's answer of 9 days is incorrect because more guests would finish the food in less time so the number of days for 30 guests is less than 6 days.

The number of days that the food can last 30 guests is 4 days.

<h3>How long will Seaview Hotel's food feed 30 guests?</h3>

More guests would eat the food faster which means that it would be finished in less days than the 6 days used by 20 guests.

To find the days the food would last 30 guests, use the inverse proportion formula:
= (Number of guests x Number of days food lasts for guests) / New number of guests

= (20 x 6) / 30

= 4 days

Full question is:

The only food provided for guests at Seaview Hotel is breakfast. The hotel has enough food to make breakfast for 20 guests for 6 days. How long would the food last 30 guests? You may assume each guest eats the same amount of food for breakfast.

Without working out the correct answer, explain why Huw’s answer of 9 days is incorrect.

Dolve for theta. С 13 4 o o A B Your answer​
ANTONII [103]

Answer:

θ ≈ 17.1°

Step-by-step explanation:

Using the tangent ratio in the right triangle

tan θ = \frac{opposite}{adjacent} = \frac{BC}{AC} = \frac{4}{13} , then

θ = tan^{-1} (\frac{4}{13} ) ≈ 17.1° ( to the nearest tenth )
