Answer:
15 feet
Explanation:
Triangle ABC is similar to triangle EDC, meaning they would’ve been congruent if it weren’t for their size.
This also means they don’t have the same side lengths but have the same proportions in comparison to each other.
The sides on the two triangles also correspond with each other. For example, line DC corresponds with line BC.
Knowing that, we can conclude that line ED also corresponds with line AB. Line ED is 12 ft and line AB is 4 ft. To get from 4 to 12, you multiply 3 (4*3=12).
Line EC also corresponds to line AC. So to calculate for line EC, we multiply the length of line AC by 3. 5*3=15, so therefore line EC is equal to 15.
Answer:
slope of r = -9/4
slope of Q = 4/9
Step-by-step explanation:
x1 y1 x2 y2
10 6 1 2
(Y2-Y1) (2)-(6)= -4 ΔY -4
(X2-X1) (1)-(10)= -9 ΔX -9
slope= 4/9
Answer:
The answer in the procedure
Step-by-step explanation:
we know that
If two triangles are similar, then the ratio of its corresponding sides is equal and its corresponding interior angles are congruent
so
substitute the values
-----> is true
Therefore
JK is parallel to MN
Triangles OMN and OJK are similar by AA Similarity Postulate ( The three interior angles are congruent)
Because
m<OKJ=m<ONM ----> by corresponding angles
m<KJO=m<NMO -----> by corresponding angles
m<JOK=m<MON -----> is the same angle
Answer:
73% of readers who are satisfied with their lives would be described as a sample statistic.
Step-by-step explanation:
The right option is D.
A) The population include all the readers of USA today.
B) The sample includes all the readers that answer the poll, wether they answer Yes or No.
C) A population statistic would be the population proportion. It is not mentioned in the text, and it would have to be estimated from the result of the sample.
D) A sample statistic is the proportion of readers that answer affirmatively the poll (p=0.73).
Answer:
126°
Step-by-step explanation:
the internal sum of the angles is always 180
28+26= 54
180-54= 126
