Answer:
B. 38
Step-by-step explanation:
A triangle is equal to 180
To find the angle you need to substract the other angles from 180
180 - 73 = 107
107 - 69 = 38
The missing angle is 38 degrees
Hope this helps dude
180-73= 107
107-68= 38
So the missing angle measurement is 38

A man walks due west for 4 km. He then
changes direction and walks on a bearing of
197° until he is south-west of his starting point.
How far is he then from his starting point? with workings
Answers
Answer:
Step-by-step explanation:
Let the starting point be B and the stopping be C as shown in the diagram below.
therefore, the angle at A will be (197-90)degree = 107degree
the angle at B is 45degree, since it is directly south west of C.
therefore the angle at C will be A+B+C=180 degree(sum angle of a triangle)
107+45+C=180
therefore, C=180-107-45=28degree
therefore, using sine rule gives;
sinA/a =sinC/c
sin107/a=sin28/4
0.9563/a=0.4695/4
0.9563/a=0.11736
therefore, a =0.9563/0.11736=8.148=8.1km(approx.)

Answers
Answer:
3a² + 13ab - 10b²
Step-by-step explanation:
(3a - 2b)(a + 5b)
Each term in each bracket multiplies each term in the other bracket.
3a(a + 5b) -2b(a + 5b)
3a² + 15ab - 2ab - 10b²

Answer:
the answer is B or q^2t^5/p^3
First simplify the p’s, we subtract and the denominator has more p’s so it stays there 5-2 =3
Next the q’s : anything to the 0 power is 1, so the p in the denominator goes away basically, and we keep the numerator with p^2
Finally, we simplify the t’s : there is only 1 t in the denominator and the majority is in the numerator , so it stays there: 6-1=5

The angle of depression calculator. How to find the angle of depression?
Since we now know what the angle of depression is, let's learn how to find it! We can determine the angle of depression using surveying equipment like an engineer's transit or a clinometer. These devices are optical instruments that have angle-measurement features and can instantly give us the angle that we need. However, we can also use mathematics to find the angle of depression. But first, we need to know two distances: the horizontal distance between the viewer and the object, and their vertical distance, as shown in the illustration below:

Mr. See weights his grades. Tests are worth 60%, quizzes are worth 25% and homework is 15%. Joey's test average is an 82, his quiz average is a 77, and his homework average is a 98. What is Joey's current grade?
Answers
Answer:
83.15
Step-by-step explanation:
Joey's current grade can be determined by weighting his scores with the weights given and adding the results
Tests = 0.6 x 82 = 49.2
Quizzes = 0.25 x 77 = 19.25
homework = 0.15 x 98 = 14.7
49.2 + 19.25 + 14.7 = 83.15

The roots of the given quadratic equation 3x² - 3x + 1 are x = [3 + √(-3)]/6 and x = [3 - √(-3)]/6 thus options (A) and (B) are correct.
What is a quadratic equation?An algebraic equation of the second degree in x is a quadratic equation. The quadratic equation is written as ax2 + bx + c = 0, where x is the variable, and a must not be zero.
As per the given equation,
3x² - 3x + 1
To find the roots of the above quadratic equation,
3x² - 3x + 1 = 0
x = [-(-3) ± √((-3)² - 4×3×1)]/(2×3)
x = [3 ± √(-3)]/6
x = [3 + √(-3)]/6 and x = [3 - √(-3)]/6
Hence "The roots of the given quadratic equation 3x² - 3x + 1 are x = [3 + √(-3)]/6 and x = [3 - √(-3)]/6".

Answers
Answer:
side length of 2
side length of 6
side length of 7
Step-by-step explanation:
So remember the two shorter lengths added together have to be greater than the longest side length
For the first answer choice we add 7 and 8
7+8=15
The two shorter sides added are not greater then the longest side so that is not the answer
For the second answer choice we add
8 and 5
8+5=13
13 is not greater than 14 so this is not the answer choice either
For the third one we add 6 and 3
6+3=9 which is not greater than 10 so this is not the answer
For the last one we add 2 and 6
2+6=8 which is greater than 7 so this one is the answer

Round to the nearest tenth.

27.8 in
Area = [? ] in?
Answers
The area of a shape is the amount of space on the shape.
The area of the shaded region is 819 inches square
How to determine the area of the shaded regionStart by calculating the area of the sector using:
[tex]A = \frac{\theta}{360}*\pi r^2[/tex]
So, we have:
[tex]A = \frac{150}{360}*\frac{22}{7} * 27.8^2[/tex]
[tex]A = 1012.05[/tex]
Next, calculate the area of the isosceles triangle using:
[tex]A = \frac 12 r^2\sin(\theta)[/tex]
So, we have:
[tex]A = \frac 12 * 27.8^2 * \sin(150)[/tex]
[tex]A = 193.21[/tex]
The shaded area is the difference between the areas of the sector and the triangle.
So, we have:
[tex]A = 1012.05 - 193.21[/tex]
Calculate the difference
[tex]A = 818.84[/tex]
Approximate
[tex]A = 819[/tex]
Hence, the area of the shaded region is 819 inches square
