The angles are 31 and 59 degrees.
Step-by-step explanation:
Let x be angle. Let 90-x be the complement of its angle. Then, x=90-x+28 since the measure of an angle is 28 degrees more than the complement.
Solving equation in Step 3 yields the following steps Add x to both sides of the equation Divide by 2 to both sides of the equation

Find the area of the polygon shown in the figure.
Answers
Answer:
16
Step-by-step explanation:
Triangle area = (1/2)*b*h
Base = b = 4
Height = h = 8
Area = (1/2) * 4 * 8 = 16
The area of the polygon shown in the figure is 16 unit square.
What is a polygon?A polygon is a closed figure made up of three or more line segments connected end to end.
Triangle is a polygon that has three sides and three vertices. It is one of the basic figures in geometry.
The area of the triangle is defined as the product of half the base and the height of the triangle.
The area of the triangle = 1/2 x b x h
WE can see from the given figure;
The Base = b = 4
The Height = h = 8
The Area of figure = (1/2) * 4 * 8
The Area of figure = 16
Hence, the area of the polygon shown in the figure is 16 unit square.

Coordinates of midpoint P → [tex](\frac{2a+0}{2}, \frac{0+2b}{2})[/tex]

(b) The Occupational Safety and Health Administration (OSHA) sets standards for a variety of occupations to help prevent accidents and other safety hazards. OSHA’s standard for the angle formed by a ladder and level ground is . The same 13-foot long ladder is placed against the building according to OSHA’s safety standard.
What is the distance between the foot of the ladder and the foot of the building? Round your answer to the nearest tenth. Show your work.
Answers
Answer:
a) 67.4°
b) 5.0 ft
Step-by-step explanation:
Now we have to use the trigonometric ratios to obtain the angle between the ladder and the level ground. Remember that the problem is a right angled triangle problem.
Let the hypotenuse of the triangle (length of the ladder) be c = 13 ft
Let the distance between the ladder and the ground be a
Let the height from the ground to the top of the ladder be b =12 ft
From;
Sinθ= opposite/hypotenuse
Sinθ= 12/13
Sinθ= 0.9231
θ=Sin^-1(0.9231)
θ= 67.4°
b) distance between the ladder and the foot of the building is obtained from
Cosθ= adjacent/hypotenuse
Adjacent= unknown
Hypotenuse= 13ft
θ= 67.4°
Cos(67.4°) = adjacent/13
Adjacent= cos (67.4°) ×13
Adjacent= 5.0 ft
Answer:
a. x ≈ 67°(nearest degree)
b. distance = 5. 1 ft (nearest tenth)
Step-by-step explanation:
A 13 ft ladder is placed on level ground leans against the side of a house . The ladder reaches a point that is 12 ft up the side of the house. The illustration forms a right angle triangle.
a. The right angle triangle formed has it opposite sides as 12 ft and it hypotenuse side as 13 ft. The angle formed between the ladder and the floor can be solved using sine ratio. Therefore,
let
x = angle
sin x = opposite/hypotenuse
sin x = 12/13
sin x = 0.92307692307
x = sin ⁻¹ 0.92307692307
x = 67.3801350509
x ≈ 67°(nearest degree)
b. If the same 13 ft ladder is placed against the building using the same angle formed .
The distance between the the foot of the ladder and the foot of the building is the adjacent side of the triangle. Therefore, using the angle formed.
cos 67° = adjacent/hypotenuse
cos 67° = adjacent/13
cross multiply
adjacent = 13 cos 67°
adjacent = 13 × 0.39073112848
adjacent = 5.07950467036
distance = 5. 1 ft(nearest tenth)

If you diluted 300 mL of 8% benzocaine lotion to 5% how much could you produce
Answers
Answer:
you are diluting it 8/5 times, or 1.6 times.
You could make 230*1.6 ml of 5 percent lotion.
If you diluted 300 mL of 8% benzocaine lotion to 5%, you will be able to produce 480 ml of 5% lotion.
What are Percentages?A percentage is a way to describe a part of a whole. such as the fraction ¼ can be described as 0.25 which is equal to 25%.
To convert a fraction to a percentage, convert the fraction to decimal form and then multiply by 100 with the '%' symbol.
The amount of benzocaine in 300 ml solution is,
Amount = 0.08 × 300 = 24ml
Since after the dilution the amount of benzocaine will be the same, therefore, we can write,
0.05 of X ml = 24 ml
X = 24/0.05
X = 480 ml
Hence, If you diluted 300 mL of 8% benzocaine lotion to 5%, you will be able to produce 480 ml of 5% lotion.

find the number of possible outcomes for creating an outfit from 4 pairs of pants 3 shirts and 4 pairs of shoes
Answers
Answer:
48
Step-by-step explanation:
This is a counting problem, so we can use the counting principle. Since there are 4 pairs of pants, 3 shirts, and 4 pairs of shoes, we do 4 * 3 * 4, which equals 48.
Using the Fundamental Counting Theorem, it is found that there are 48 possible outcomes for the outfit.
What is the Fundamental Counting Theorem?It is a theorem that states that if there are n things, each with [tex]n_1, n_2, \cdots, n_n[/tex] ways to be done, each thing independent of the other, the number of ways they can be done is:
[tex]N = n_1 \times n_2 \times \cdots \times n_n[/tex]
In this problem, the options are as follows:
There are 4 possible pairs of paints, hence [tex]n_1 = 4[/tex].There are 3 shirts, hence [tex]n_2 = 3[/tex].There are 4 pairs of shoes, hence [tex]n_3 = 4[/tex].Hence, the total number of options given by:

What is the area of a circle with a diameter of 36 millimeters? mm square use 3.14 pi
Answers
Answer: 1018 sq. mm.
Step-by-step explanation:
Area = πr^2
= π x 18^2
= 324π
The required area of a circle is 1018 millimeters² with a diameter of 36 millimeters.
What is the area of the circle?The area of the circle is equal to the product of the square of the radius of the circle and pi.
A = πr²
where 'r' is the radius of the circle
As per the question, we have
The diameter of the circle = 36 millimeters
The radius of the circle = diameter/2
The radius of the circle = 36/2 = 18 millimeters
The area of the circle = πr²
The area of the circle = π × 18²
The area of the circle = 3.14 × 324
The area of the circle = 1018
Thus, the required area of a circle is 1018 millimeters² with a diameter of 36 millimeters.
