<h3>
Answer: Angle C is 76 degrees</h3>
===================================================
Explanation:
Since AE = BE, we know that triangle ABE is isosceles with A = B as the congruent base angles (it might help to rotate the triangle 90 degrees clockwise). The congruent base angles are always opposite the congruent sides of an isosceles triangle.
Focus on triangle ABE. Let's find the missing angle E.
A+B+E = 180
55+55+E = 180
110+E = 180
E = 180-110
E = 70
So angle BEA = 70 degrees
This means angle DEC is also 70 degrees. Angles BEA and DEC are congruent vertical angles.
--------------------
Now focus on triangle DEC. We just found E = 70. The diagram shows D = 34. Use these items to find C
D+E+C = 180
34+70+C = 180
104+C = 180
C = 180-104
C = 76
Angle C is 76 degrees
Answer:
45.24%
Step-by-step explanation:
Given that:
Correlation Coefficient (r) between number of hours a child play video games and number of minutes spent doing homework = - 0.74
The Coefficient of determination (r²) gives the percentage of variation in the dependent variable which can be explained by the independent variable.
Hence, the r² value = (-0.74)² = 0.5476 ; 54.76% which is about 55% variation in the number of minutes spent doing homework can be explained by the number of hours a child plays video games.
Hence the unexplained variance due to differences in children's ages is (100% - 54.76%) = 45.24%
