Hey there!
All the angles in a triangle add up to 180.
So,
70+30+x=180
100+x=180
x=80
I hope this helps!

Given that y varies directly with x in the above table, if the value of x is 5, the value of y is 15.
<h3>How to calculate direct variation?</h3>
According to this question, a 2-column table with 5 rows is given.
- Column 1 is labeled x with entries 1, 3, 6, 9, 12
- Column 2 is labeled y with entries 3, 9, 18, 27, 36
If y varies directly with x, the mathematical representation is as follows:
y = kx
Since y = 3, when x = 1
3 = k × 1
k = 3
The relationship between x and y is as follows: y = 3x
Therefore, if the value of x is 5, the value of y = 3 × 5 = 15.

According to the 3:1 ratio, you expect, out of a population of 1000 people, 750 non-hemophilia and 250 hemophilia.
The chi-square value can be calculated by the formula:
where:
O = observed value = 210
E = expected value = 250
Therefore:
χ² = (210 - 250)² / 250
= 6.4
Now, look at a χ<span>² distribution table, in order to find the p-value. In this case, you have only 1 degree of freedom and the closest </span>χ<span>² is 6.6 which corresponds to a p-value of 0.01.
Since p < 0.05, which is the minimum value generally accepted, we can say that the data do not support the hypothesis.</span>

The answer is A and B
Increasing and linear
Since these are both congruent figures, there lengths will also be congruent to one another. The triangles, VZX is congruent to RPQ. If your trying to figure out the measure of RQ, you have to look at the letters of each triangle name.
RQ is the 1st and 3rd third letter of triangle RPQ.
This means VX is congruent to RQ!
They gave us the measurement of VX which is 4cm!!!
So if RQ is congruent to VX and VX = 4cm, then
RQ is 4cm!!
