In the first question,
Since D is the midpoint of line segment AC.
therefore, AD=DC.
In triangles, ABD & CBD.
Since, AB is congruent to CB and BD is a common side between those two triangles.
Therefore, AD is congruent to DC.
Finally, in triangles DEA & DEC
Since, ED line segment is a common side between those triangles and the measure of angle EDA is as the same of angle EDC which are equal to 90 degrees and AD is congruent to DC.
Therefore, triangle EDA is congruent to triangle EDC ( you have to take care of the triangle order letters in congruence) and EC is congruent to EA.
Answer:
X=0.500
Step-by-step explanation:
maths
<span>1. Two angles are complementary. One angle measures 50°. What is the measure of the other angle?
</span>complementary, sum of the angles = 90
<span>
so 90 -</span> 50 = 40
<span>
answer is
C.40°
2.Two angles are supplementary. One angle measurement is 30° more than the other. What is the measure of the smaller angle?
</span>supplementary, sum of the angles = 180
One angle measurement is 30° more than the other.
so both angles are 75 and 105
105 is 30 more than the other angel of 75
answer
measure of the smaller angle is 75
so it's D.75°
Answer:
D. 40
Step-by-step explanation:
Interquartile range is the difference between the upper quartile value (Q3) and the lower quartile value (Q1).
In a box plot, Q1 is located at the beginning of the edge of the rectangular box from our left, while the Q3 is located at the end of the edge of the rectangular box to our right.
Interquartile range for City A = 70 - 40 = 30
Interquartile range for City B = 80 - 40
Therefore, city B has greater variability. The interquartile range is 40.
