Answer:
c = 49°
Step-by-step explanation:
Inside of the triangle angles:
- c–18°
- c–16°
- 180°-(c+15) → -c+165
these angles sum up to total 180° angle
-c+165+c-16°+c–18° = 180
c +131 = 180
c = 180° - 131°
c = 49°
Answer:
j = 44/3
Step-by-step explanation:
j varies jointly as g and v. This can be represented mathematically as:
.............(1)
Where k is a constant of proportionality
j = 2 when g = 4 and v = 3
Substitute these values into equation (1)
2 = k * 4 * 3
2 = 12 k
k = 1/6
when g = 8 and v = 11:
j = (1/6) * 8 * 11
j = 44/3
Answer: 8m^2 - 7x^2 + 10mx
Step-by-step explanation:
Answer:
B
Step-by-step explanation:
You use PEDMAS to evaluate the perfect number so in the PEDMAS it says addition then to subtraction so, the addition goes first. And when you have both addition you go left to right :)
Answer: OPTION D.
Step-by-step explanation:
Given the equilateral triangle shown in the figure, you need to find the value of the altitude "a".
In order to find the altitude, you can use the following Trigonometric Identity:

In this case you can identify that:

Therefore, you can substitute values into
:

Finally, you must solve for the altitude "a". Then, this is:

Notice that this result matches with the value shown in Option D.
