In ΔABC, the measure of ∠C=90°, AC = 56, BA = 65, and CB = 33. What ratio represents the sine of ∠A?
Answers
Answer:
80 degree
Step-by-step explanation:
The ratio 33/65 represents the sine of ∠A and the value of the angle A is 30.51° if the measure of ∠C=90°, AC = 56, BA = 65, and CB = 33.
What is a right-angle triangle?It is defined as a triangle in which one angle is 90 degrees and the other two angles are acute angles. In a right-angled triangle, the name of the sides are hypotenuse, perpendicular, and base.
Triangle ABC represents a right-angle triangle(refer to attached picture)
We know sin is the ratio of the opposite to the hypotenuse.
Let's suppose the ∠A is α
From the figure:
[tex]\rm Sin\alpha = \frac{BC}{AB}[/tex]
[tex]\rm Sin\alpha = \frac{33}{65}[/tex]
Sinα = 0.507
α = 30.51°
Thus, the ratio 33/65 represents the sine of ∠A and the value of the angle A is 30.51° if the measure of ∠C=90°, AC = 56, BA = 65, and CB = 33.

Answer:
In philosophy and psychology, a nativist is a person who believes in an innate understanding of particular concepts. This includes innate knowledge and ideas which occur at birth and are not acquired through learning and experience.
In United States history, a nativist is a person who opposes immigration of any kind which is deemed "undesirable" and who advocates for the exclusive interests of native-born citizens, often from longtime American families. Nativists disliked Catholics as well as immigrants and minorities.
A famous nativist organisation of America is the Know-Nothing party of the 1840s.

What are 3 consecutive multiples of 3 if 2/3 the sum of the first two numbers is 1 greater than the third number?
Answers
Answer:
the numbers are 15, 18, 21
Step-by-step explanation:
let the 3 consecutive multiples of 3 be:
3x, 3(x+1), 3(x+2)
(2/3)(3x + 3(x+1)) =3(x+2)+1
(2 /3)(6x+ 3) = 3x+6+1
2(2x+1) = 3x + 7
4x + 2 = 3x + 7
x = 5
so:
3x = 15
3(x+1) = 18
3(x+2) = 21
the numbers are 15, 18, 21

Yolanda makes wooden boxes for a crafts fair, She makes 100 boxes like the one shown, and she wants to paint all the outside faces.
A. Find the surface area of 100 boxes
B. One can of paint will cover 14,000 square inches. How many cans of paint will Yolanda need to buy?
L = 10
W = 6
H = 4
Answers
A box has 4 sides, two short sides which are width by height and two long sides which is length by height.
A) Surface area = 2(LxH) + 2(WxH)
Surface area = 2(10x4) +2(6x4)
Surface area = 2(40) +2(24)
Surface area = 80 + 48
Surface area = 128 square inches for each box.
128 square inches x 100 boxes = 12,800 square inches.
B) 1 can covers 14,000 square inches which is greater then the total of the 100 boxes, so she will need to buy 1 can of paint.

Assume that adults have IQ scores that are normally distributed with a mean of and a standard deviation . Find the probability that a randomly selected adult has an IQ less than . The probability that a randomly selected adult has an IQ less than is
Answers
Answer:
the probability when the IQ is lower than 136 is 0.9641
Step-by-step explanation:
Given that
The mean is 100
The standard deviation is 20
We need to find out the probability when the IQ is lower than 136
So,
z value equivalent to 136 = (136 - 100) ÷ 20 = 1.8
Now
p (z < 1.8) = 0.9641
hence, the probability when the IQ is lower than 136 is 0.9641

What is line?A line is a straight one-dimensional figure having no thickness and extending infinitely in both directions. A line is made of a set of points which is extended in opposite directions infinitely. It is determined by two points in a two-dimensional plane. The two points which lie on the same line are said to be collinear points.
Given:
The given figure shown as four lines are given AB , CD ,EF , CD ,GH and EF.
According to given question we have
Parallel = AB and CD
Perpendicular = EF and CD
Neither parallel nor perpendicular lines: GH and EF
Parallel lines are those lines that are equidistant from each other and never meet, no matter how much they may be extended in either directions
Perpendicular lines are lines that intersect at a 90-degree angle.
Therefore , the Parallel lines are AB and CD and Perpendicular lines are EF and CD.

Explanation:
The formula we'll use to find the surface area is:
SA = 4*pi*r^2
In this case, the radius is r = 2.3 meters
SA = 4*pi*r^2
SA = 4*pi*(2.3)^2
SA = 66.47610054996
SA = 66.48 square m
You'll type the expression you see for step 2 into your calculator to get the result of step 3. The result is approximate. Let your calculator handle the decimal digits of pi as your teacher instructs. The last step is us rounding to two decimal places. The units for the surface area are in square meters, because we can effectively unwrap the outer surface (think of it like unwrapping a present) to lay it out flat.
