Enter the measure of ZCAB to the nearest hundredth degree.
Step-by-step explanation:
sinA=p/h
sinA=12/15
A=sin-¹(4/5)=53.13=53°
<CAB=53°
The measure of ∠CAB is 53°.
What is Trigonometry?The trigonometric function, which comprises the sine, cosine, tangent, cotangent, secant, and cosecant, is one of the six mathematical operations used to describe the side ratios of right triangles (csc).
As per the given data:
From the given diagram, we can clearly understand that the triangle is a right-angled triangle which is right-angled at C.
We have to find out the measure of ∠CAB.
The lengths of the sides BC and AB is also given in the diagram.
For finding out the measure of ∠CAB we can consider BC as the perpendicular and AB as the hypotenuse, and then we have to use the appropriate trigonometric ratio.
The length of the perpendicular BC = 12 units
The length of the hypotenuse AB = 15 units
For relating perpendicular and hypotenuse, we can use the sin trigonometric ratio.
sinθ = Perpendicular / Hypotenuse
sinθ = BC / AB
sinθ = 12 / 15
sinθ = 4 / 5
θ = 53°
The measure of ∠CAB is 53°.
Hence, The measure of ∠CAB is 53°.

Item 4 Write a proportion to find how many points x a student needs to score on a test worth 50 points to get a test score of 40%
Answer:
20 points
Step-by-step explanation:
We need to find how many points x a student needs to score on a test worth 50 points to get a test score of 40%.
Let x be the number of points.
ATQ,
[tex]\dfrac{x}{50}=\dfrac{40}{100}\\\\x=\dfrac{50\times 40}{100}\\\\x=20[/tex]
Hence, a student needs 20 points to get a score of 40%.

A line passes through the point (8, -9) and has a slope of 3/4 . Write an equation in point-slope form for this line.
Answer:
y+9=3/4(x-8)
Step-by-step explanation:
y-y1=m(x-x1)
y-(-9)=3/4(x-8)
y+9=3/4(x-8)
What's -2/9 * 5/6? I'm a bit stuck.
Answer:
-2/9*5/6
As it is multiplication we can directly multiply them.
Thus we will get,
(-2*5)/(9*6)
-10/54
And now by converting into the simplest form we will get,
-5/27
And this is the final answer.

Step-by-step explanation:
Triangle formula:
point slope and slope intercept
Answer:
Step-by-step explanation:
Observe what happens to y if we move from x = 1 to x = 9: y decreases by 2. Thus, the slope of the line in question is m = rise / run = -2/8, or -1/4.
Writing the equation in point-slope form, y - k = m(x - h), we get:
y - 7 = (-1/4)(x - 1) (point-slope form)
Solving for y results in the slope-intercept form:
y = 7 - x/4 + 1, or
y = (-1/4)x + 8 (slope-intercept form)

Name two points on the line y = 6x. Does it describe a
proportional relationship?
Answer:
b. Non-proportional
Step-by-step explanation:
A table of values that represents a proportional relationship will have the same ratio of every pair in the given table. That is, y/x will result in the same value all through for every given pair.
The table of values given does not show a proportional relationship, because the ratio of y to x of each given pair of values are different and unequal:
y/x = 3/1 ≠ 5/2 ≠ 7/3 ≠ 9/4
Therefore, it is non-proportional.

[Easy Question] Answer this with evidence of the answer that you provided with me!
Answer:
48
To start you will find the area as if it was a rectangle. To do that you have to do 8x12. 8x12 = 96, but to find the area of a triangle you take the area of the rectangle and divide it by 2. 96 divided by 2 is equal to 48.
There are other methods of solving this but I think this is the easiest way!

which images shows a reflection
I'll Give You Some Hints:
Let's Look at C.
In C, the triangle is translated 2 units to the right. Which means that it cannot be a reflection.
Let's Look at B.
In B there is a sideways triangle. That means it's a Rotation. Which means it's not Reflected.
Lastly, Let's Look at A.
To get from the original triangle to the triangle in A, you have to reflect twice. Once along a vertical line, and then along a horizontal line.
