In JKL, k=4.1 cm,j=3.8 cm and angle J=Q3^ Find all possible values of angle K , to the nearest inch of a degree .
Answers
Answer:
74.0°
Step-by-step explanation:
In triangle JKL, k = 4.1 cm, j = 3.8 cm and ∠J=63°. Find all possible values of angle K, to the nearest 10th of a degree
Solution:
A triangle is a polygon with three sides and three angles. Types of triangles are right angled triangle, scalene triangle, equilateral triangle and isosceles triangle.
Given a triangle with angles A, B, C and the corresponding sides opposite to the angles as a, b, c. Sine rule states that for the triangle, the following holds:
[tex]\frac{a}{sin(A)}=\frac{b}{sin(B)}=\frac{c}{sin(C)}[/tex]
In triangle JKL, k=4.1 cm, j=3.8 cm and angle J=63°.
Using sine rule, we can find ∠K:
[tex]\frac{k}{sin(K)}=\frac{j}{sin(J)} \\\\\frac{4.1}{sin(K)}=\frac{3.8}{sin(63)} \\\\sin(K)=\frac{4.1*sin(63)}{3.8}\\\\sin(K)=0.9613\\\\K=sin^{-1} (0.9613)\\\\K=74.0^o \\[/tex]

Reuben hires a car. It costs £150, plus 85p for each mile he travels. When Reuben hires the car, its mileage is 27612 miles. When Reuben returns the car, its mileage is 28361 miles. How much did Reuben pay to hire the car?
Answers
Answer:
Cost of hiring a car = £63,815
Step-by-step explanation:
Cost of hiring a car = 150 + 85p
When Reuben hires the car, its mileage is 27612 miles. When Reuben returns the car, its mileage is 28361 miles.
Number of miles Reuben travelled = 28,361 miles - 27,612 miles
= 749 miles
Cost of hiring a car = 150 + 85p
= 150 + 85(749)
= 150 + 63,665
= 63,815
Cost of hiring a car = £63,815

Answer: B 89 degrees
Step-by-step explanation:
The triangle angle sum theorem states that the angles of a triangle sum to 180 degrees. Since we know two of the angle measures we can find the missing angle. 60 + 31 = 91 degrees.
180 - 91 = 89 degrees

Answers
Answer:
ubstitute the value of the radius r = 8.0 cm height h = 12.0 cm into the formula to find the volume. Pi (π) is approximately equal to 3.14 .
π x 82 cm2 x 12 cm
Raise 8 cm power of 2
π x 64.0 cm2 x 12 cm
Multiply 64.0 cm2 and 12 cm
π x 768.0 cm3
Combine π and 768.0 cm3
The result can be shown in multiple forms.

Answers
Answer:
6,15
Step-by-step explanation:
A dilation is the changing of a size. A scale factor is a proportional number that tells us how much we change a shape.
If the scale factor is over 1, the new image will stretch.
If the scale factor is under 1, the new image will shrink
Since we are asked to find A' (which is prime notation) meaning that we are asked to find the coordinates where A' is at on the new image.
Since the scale factor is 3,
3 is greater than 1 so it will stretch.
Now, multiply 3 to each number
to find it new location.
[tex] \frac{2}{5} \times \frac{3}{3} = \frac{6}{15} [/tex]
So the coordinates are at 6,15
Answer:
I'm pretty sure you multiply each number in (2,5) by the 3 to get new coordinates of (6,15)
that's the only answer that could fit :)
