Answer:
Let the sides be a and b
a^2 + b^2 = c^2 = 29^2 = 841
a^2 + (a + 1)^2 = 841
a^2 + a^2 + 2 a + 1 = 841
2 a^2 + 2 a = 840
a (a + 1) = 420
21 * 20 = 420 trial and error
So the sides are 20 and 21
20^2 + 21^2 = 29^2
The research question is important to a researcher as it helps in solving the issue that the researcher wants to solve.
- The research topic will be "Social media has an effect on the behavior of children".
- The research question will be "what effect does social media has on the effects of the behavior of children".
- The null hypothesis will be "there is no statistical significance between social media and children's behavior".
- The alternative hypothesis will be "there is a statistical significance between social media and children's behavior".
- The null hypothesis will be rejected when the p-value is equal to the significance level or it's less than it.

Answer:
ve a chupar una polla perra culo gay
Step-by-step explanation:
Answer:
B. 31°, 106°, and 43°.
Step-by-step explanation:
the sum of the measures of the angles in a triangle add up to 180°, so:
3x+1+11x-4+5x-7=180
19x-10=180
19x=190
x=10
now that we know x is equal to 10, we can find the three angle measures:
3x+1 -> 3(10)+1 = 31°
11x-4 -> 11(10)-4 = 110-4 = 106°
5x-7 -> 5(10)-7 = 50-7 = 43°
so, the answer is B.
