To find 1. all you have to do is 165/30 and you get $5.50. To find 2. you have to add 165+45 you get 210. then divide 210/40 and you get 5.25
Answer:
<em>The height of the bullding is 717 ft</em>
Step-by-step explanation:
<u>Right Triangles</u>
The trigonometric ratios (sine, cosine, tangent, etc.) are defined as relations between the triangle's side lengths.
The tangent ratio for an internal angle A is:
The image below shows the situation where Ms. M wanted to estimate the height of the Republic Plaza building in downtown Denver.
The angle A is given by his phone's app as A= 82° and the distance from her location and the building is 100 ft. The angle formed by the building and the ground is 90°, thus the tangent ratio must be satisfied. The distance h is the opposite leg to angle A and 100 ft is the adjacent leg, thus:
Solving for h:
Computing:
h = 711.5 ft
We must add the height of Ms, M's eyes. The height of the building is
711.5 ft + 5 ft = 716.5 ft
The height of the building is 717 ft
Answer:
x=-4
Step-by-step explanation:
These two angles have to equal 180 because they are opposite of each other. Therefore, the equation will be 129+x+x+59=180. You add all common terms. 2x+188=180. You want to isolate x so you have to subtract both sides by 188. Therefore, the equation will be 2x=-8. Divide both sides by 2 to isolate x. x=-8/2. This is equal to x=-4.

Answer:
,
Step-by-step explanation:
In this problem,, we are told that Mr Nelson needs 5 1/2 yards of fabric to make two dresses. the problem then asks us to find out how much fabric it will take to make only one of the dresses. this means that in order to find out how much fabric is needed to make only one of the two dresses,, we need to divide the total amount of fabric by two. the equation will look like the following:
5 1/2 ÷ 2
the first step to solving this is to convert the mixed number to an improper fraction
11/2 ÷ 2
now,, you can turn the 2 into a fraction and changed the sign because dividing is equivalent to multiplying with the reciprocal value.
11/2 × 1/2
you must then multiply the fractions
11/4
finally,, you need to simplify the fraction to find the answer
2 3/4 yards
since you cannot simplify any further,, the correct answer to your question is A, 2 3/4 yards.
