Angle A is a supplementary to Angle B. If < b = 65 degrees what is the value of x if < A = 5x -20 ?
Answer:
x = 27
Step-by-step explanation:
Supplementary angles add up to 180 degrees
65 + 5x - 20 = 180
45 +5x = 180
5x = 135
x = 27

Answer:
so practically, the only thing that we would do would be doing is converting the meters to feet 12.4 meters convert to feet would be 40.6 ft :)
Answer: To be exact, about 40.68241 feet, you can round to the nearest hundredths place to get 40.67
Given: Quadrilateral ABCD is a kite. Prove: ΔAED ≅ ΔCED Kite A B C D is shown. Diagonals are drawn from point A to point C and from point B to point D and intersect at point E. It is given that quadrilateral ABCD is a kite. We know that AD ≅ CD by the definition of . By the kite diagonal theorem, AC is to BD This means that angles AED and CED are right angles. We also see that ED ≅ ED by the property. Therefore, we have that ΔAED ≅ ΔCED by .
Answer:
1. kite 2. perpendiclular 3. reflective 4. HL
Step-by-step explanation:
I hope this helps :)
Answer:
We know that AD ≅ CD by the definition of kite. By the kite diagonal theorem, AC is perpendicular to BD. This means that angles AED and CED are right angles. We also see that ED ≅ ED by the reflexive property. Therefore, we have that ΔAED ≅ ΔCED by HL.
Step-by-step explanation:
We know that AD ≅ CD by the definition of kite.
- adjacent sides in a kite are congruent
By the kite diagonal theorem, AC is perpendicular to BD.
- the kite diagonal theorem states that diagonals of a kite form right angles because they are perpendicular to each other.
We also see that ED ≅ ED by the reflexive property.
- any side or angle congruent to itself is identified by the reflexive property
Therefore, we have that ΔAED ≅ ΔCED by HL.
- the triangles formed are all right triangles, so we can they that the two triangles are congruent to each other by the Hypotenuse Leg theorem.
The total price for a computer and a
printer was $1039. If the computer
cost $750, how much did the printer
cost?
Answer:
$289
Step-by-step explanation:
If you know the cost of one of the two items, you can subtract that item from the total in order to find the price of the second item
So: total price - computer price = printer cost
So: $1039- $750 = $289
The printer is $289

Factorize (4y-5)²+80y
Answer:
16y^2+40y+25
Step-by-step explanation:
[tex] {16y}^{2} + 40y + 25[/tex]
Step-by-step explanation:
(4y−5)^2+80y
Use binomial theorem (a−b)^2=a^2−2ab+b^2 to expand (4y−5)^2.
16y^2−40y+25+80y
Combine −40y and 80y to get 40y.

Give your answer correct to 1 decimal place,
You must show all your working,
On the same line as your final answer you must write "to 1 decimal place".
Answer:
Since the sign of the equation changes from positive to negative when evaluating from 8.4 to 8.3, then x = 8.3 seems to be a reasonable value. Finally, the solution to 1 decimal place is:

2 y = (1865
Answer:
y = 18/5(11)
Step-by-step explanation:
If y varies directly as x, this is expressed as;
y∝x
y = kx
k is the constant of proportional constant
if y = 18 and x = 5
18 = 5k
k = 18/5
to get the expression that can be used to find the value of y when x is 11
y = kx
y = 18/5(11)

Staples sells boxes of pens for ($10) and rubber bands for ($24). Leona ordered a total of 24 cartons for $210. How many boxes of each did Leona order? Hint: Let P = Pens.
Answer:
Leona ordered 19 boxes of pens and 5 rubber bands
Step-by-step explanation:
Let there are p pen and b rubber bands.
ATQ,
p+b = 24 ...(1)
and
10p+4b = 210 ...(2)
Multiply equation (1) by 10.
10p+10b = 240 ...(3)
Subtract equation (2) from (3).
10p+10b-(10p+4b ) = 240-210
6b = 30
b = 5
Put the value of b in equation (1).
p+5 = 24
p = 19
Hence, Leona ordered 19 boxes of pens and 5 rubber bands.
