Answer:
Measure of BC = 10.
Step-by-step explanation:
This is an isosceles triangle because the 2 base angles are both 50 degrees.
So the 2 sloping sides AB and BC are also equal.
Answer:
URGENT
Debug the following:any one free out
sin theta equals to cos theta then the value of sin 2 theta
For this case we have a function of the form
, where 
We must find the value of the function when
, that is, we must find f (3). So:

So
Answer:

<h2>y + 1 = -3(x - 10)</h2>
Here's the formula:
y - y1 = m(x - x1)
Substitute numbers accordingly:
y1: so 1 goes in the y1 spot (you switch the signs because it was already negative)
x1: and 10 goes to the x1 spot
m: -3 belongs in m
<span><u><em>Answer:</em></u>
The difference between successive terms is 10
<u><em>Explanation:</em></u>
To know the factor by which a certain pattern is increasing/decreasing, you need to subtract its successive terms.
If the subtraction gives you 10, this means that the pattern is increasing by 10
<u>Examples:</u>
<u>10, 20, 30, 40, 50, .....</u>
20 - 10 = 10
30 - 20 = 10
40 - 30 = 10
50 - 40 = 10
The difference between each two successive terms is 10. This means that each time we add 10 to the number we have in order to get the next one.
Therefore, this pattern is increasing by 10
<u>37, 47, 57 , .....</u>
47 - 37 = 10
57 - 47 = 10
The difference between each two successive terms is 10. This means that each time we add 10 to the number we have in order to get the next one.
Therefore, the pattern is increasing by 10
