(20/Sin 67) = (21/Sin A)
Cross multiply
21Sin67 = 20SinA
Divide by 20
(21Sin67)/20 = SinA

A = Sin^-1 (21Sin67)/20 = 75 degrees

Estimate the perimeter of the figure to the nearest tenth.
Vlad [161]

Answer:

The Perimeter of the Figure to the nearest tenth is 18.7 units

Step-by-step explanation:

Please note I have attached an edited version of your sketch to aid my solution. Now this question can be solved in multiple ways. Here, we shall see one of them. Looking at the original sketch, we can see that the figure is actually a combination of a Triangle (Figure 1 in my sketch) and a rectangle (Figure 2 in my sketch). So we can simply find the sides of a Triangle and the sides of a Rectangle and add them. Perimeter on Figure 1:The Perimeter of a Triangle is given by the Sum of the three sides as:

AT=a+b+c

Perimeter on Sketched Figure:The perimeter of the total figure will be two sides of the triangle and the three sides of the rectangle (as the one adjacent between Fig. 1 and 2 can not be taken into account). Thus we need to find 5 different sides and add them together. Now since the figure is on a graph paper, we can read of the size of some sides, thus the left side of the triangle is  units and the base of the triangle is also  units. Now to find the last unknown side we can take Pythagorian theorem, since our triangle is a Right triangle, (i.e. one angle is 90°). Pythagoras states that the squared of the hypotenuse of a right triangle is equal to the sum of the squares of the other two legs of the triangle (where the hypotenuse side is always across the 90° angle. So here we can say that: where  is the hypotenuse and our unknown side. So plugging in values and solving for   we have: units.

Perimeter on Figure 2:

The Perimeter of the Rectangle is given by:

Ar=2(w+l)

Tony has $18 to buy apples and bananas for a fruit salad. Apples cost $2 per pound and bananas cost $1 per pound. Write and grap
nlexa [21]

The inequality to describe the situation is; 2a + 1b <= 18

Since according to the question;

  • Tony has $18 to buy apples and bananas for a fruit salad.

  • Apples cost $2 per pound and bananas cost $1 per pound.

  • Let the number of apples bought be; a

  • Let the number of bananas bought be; b

Therefore, the inequality to describe the situation is;

  • 2a + 1b <= 18

This means that the cost of the total number of apples and bananas bought by Tony is; less or equal to $18.

Additionally, Two possible combinations of pounds and apples that Tony can buy are;

  • Tony buys 9 apples and no banana

  • Tony buys 18 bananas and no apple.
