Ok so remember
when 2 lines intersect the 2 opposite angles that face each other are equal measure
also, remember that a straight line=180
so
therefor BEA=CED and we want to find BEA, also
BED=180 so
BEC+CED=BED=180
aka
6x+7+5x-3=180
solve
6x+7+5x-3=180
combine
11x+4=180
subttract 4
11x=176
diivde 11
x=16
CED=AEB
CED=5x-3
subsitute
CED=5(16)-3
CED=80-3
CED=77
CED=77=AEB
answer is 77 degreees
Answer:
<em>JM = 5 mm </em>
Step-by-step explanation:
Δ JMK is the right angled triangle ⇒ JM² = JK² + KM²
JM² = 3² + 4²
<em>JM = 5 mm</em>
Answer: for me it must be A or C I have a picture how I find my answer.
Step-by-step explanation: Hope this help :D
Answer:
Step-by-step explanation:
Let base be b, height be h
h = 7+b or we can say that b = h -7
A = 15 cm²
General formula for area of a triangle
A = b · h
Substitute what we know to find the height h
15 = (h-7) · h
15 = h² -7h
0 = h²-7h -15
h = (7 ±√49 + 4·1·15)/2
h = (7 ±√109)/2
h ≈ -1.72 reject this solution because height cannot be negative
h ≈ 8.72 cm
Answer:
The best measure of center for this dot plot is the median.
Choice A
Step-by-step explanation:
measures of center or location of a data set include;
the mean
the mode
the median
If a data set is symmetric or approximately normal then the best measure of center is the mean. On the other hand, for an asymmetric data with outliers the best measure of center is the median since it is robust to outliers.
