The definition of the interior angles of a triangle states that
interior angles of a triangle add up to 180º.
This means we can find the measure of <CED:
<C
ED + <E
CD + <C
DE = 180º
<C
ED = 180º - <E
CD - <C
DE
<C
ED = 180º - 43º - 35º
<CED = 102º
By the definition of vertical angles states that a pair of vertical angles are congruent.
This means <C
ED = <A
EB
If <C
ED = 102º
Then
<AEB = 102º
By definition of the interior angles of triangles:
<AEB + <EBA + <BAE = 180º
<AEB = 102º
<EBA = 18º
102º + 18º + <BAE(<A) = 180º
<BAE = 180º - 102º - 18º
<BAE = 60º
<BAE is another way to say <A

m∠A = 60º</span>
Answer: 81 m^2
Step-by-step explanation:
Parallelogram:
9 × 5 = 45
Triangle:
8 × 9 = 72
72 ÷ 2 = 36
Add:
45 + 36 = 81 bro look i even did an explation can u plz mark brainlist
School sells lunch for $5.50 dollars per day for 5.3 days, if sally has $25.60 than will she be able to buys lunch for those 5.5 days
1- Multiply 5.5 times 5.3 (number of days)
2-Take 25 and divide it by that number
Answer:
0.0321
Step-by-step explanation:
This can be found by binomial probability distribution as the probability of success is constant. There are a given number of trials. the successive tosses are independent.
Here n= 5
The probability of getting a four in a roll of a die = 1/6
The probability of not getting a four in a roll of a die = 5/6
The probability of getting exactly three 4s in five throws is given by
5C3 (1/6)³ (5/6)² = 10 (0.0046) (0.694)= 0.0321
