The three inside angles (A,B and C) of a right-angled triangle are in the ratio 7:18:11. Th smallest angle is 35. Work out angle
lions [1.4K]

Answer:

<A = 35degrees

<B =90degrees

<C = 55degrees

Step-by-step explanation:

Given the ratios of a triangle as 7:18:11

Total ratio = 7+18+11

Total ratio = 36

Since the smallest angle is 35degrees, hence <A = 35degrees

Get angle B;

<B = 18/36 * 180 (sum of angle in a triangle is 180degrees)

<B = 1/2 * 180

<B = 90degrees

Get angle C;

<C = 11/36 * 180

<C = 11 * 5

<C = 55degrees

Hence the value of A, B and C are 35, 90 and 55 degrees repectively

Refer to this sketch of a warehouse <br><br><br>please answer please and thank you
stiv31 [10]

Answer:

2) 12,000 ft²

3) 30 gallons.

Step-by-step explanation:

2) 1. You can calculate the lateral surface area of the exterior walls of the warehouse by applying the formula shown below:

LA=h(2l+2w)

Where <em>h</em> is the height, <em>l</em> is the lenght and <em>w</em> is the width.

2. Substitute values and you obtain that the lateral area is:

LA=20ft[(2*200ft)+(2*100ft)]

LA=12,000ft^{2}

3) You know that 1 gallon of paint covers 400 ft², therefore for 12,000 ft² are needed the following number of gallons (which is represented by <em>x</em>):

x=\frac{(1gallon)(12,000ft^{2})}{400ft^{2}}=30gallons
