AE and EC are congruent because it's given that E is the midpoint of AC. However, DE and EB cannot be congruent because it does not state that point E is the midpoint of DB.
You cannot assume that all the triangles DEA, AEB, BEC, and CED are all congruent just from being given that E is the midpoint of AC. You would need to be given other information such as "Quadrilateral ABCD is a parallelogram. "
The formula for finding the area of a circle can be written in many ways. If the radius is given, the formula is A=πr², where A=area, π=22/7 or 3.14, and r is the radius.
If the diameter is given, then the formula is A=1/4πd², where A is the area, π is 22/7 or 3.14 and d is the diameter
Given that the diameter is 46 inches and π=22/7 or approximately 3.14, the formula we can use is A=1/4πd² where A=area, π is 22/7 and d is 46
A=1/4*22/7*46*46
A=16662.57 inches² (It is rounded to nearest hundredth)
50×40=2000

Answer:
128°
Step-by-step explanation:
90+90+52= 232°
360°- 232° = said answer above
Answer:
x = 2.3202
Step-by-step explanation:
Given equation:
on taking log both sides, we get
now,
using the property of log function
log(aᵇ) = b × log(a)
therefore,
we get
(3x-5)log(10) = xlog(7)
now,
log(10) = 1
and
log(7) = 0.84509
thus,
( 3x - 5 ) × 1 = 0.84509x
or
3x - 0.84509x - 5 = 0
or
2.15491x = 5
or
x = 2.3202
