please help me, I'm stuck on the second one. Also for i) i got angle ABD because angles in a semicircle measures 90 degree and OAX because the angle between the tangent and a radius is 90 degrees
Answers
Answer:
i)
DA is diameter and AX is tangent to circleYour answer is correct
m∠ABD = 90°, m∠DAX = 90°ii)
Given m∠BAX = 42° and ∠DAB is complementary with BAX ⇒
m∠DAB = 90° - 42° = 48°DC = BC ⇒ intercepted arcs are same ⇒
∠CDB = ∠BDCmDC = mCB ⇒ mDCB = ∠DAB = 48° ⇒
m∠CDB = m∠BDC = 1/2*48 = 24°iii)
∠CBA
∠CBA is supplementary with ∠ADC as opposite angles of cyclic quadrilateral (∠ADB = ∠BAX = 42°)
m∠ADC = m∠ADB + m∠CDB = 42° + 24° = 68°m∠CBA = 180° - m∠ADC = 180° - 68° = 112°∠BAE
EA║CB and AB is transversal ⇒ CBA and BAE are supplementary angles:
m∠BAE = 180° - 112° = 68°∠DCE
∠DCE = ∠DCB - ∠BCEm∠DCB = 180° - m∠DAB = 180° - 48° = 132°m∠BCE = 180° - m∠BAE = 180° - 68° = 112°∠DCE = 132° - 112° = 20°Related Questions
If you want 2 cookies and you only have.50 cents and the cookies cost 10 dollars how much money will you have to get if you only have.50 cents
Answers
Answer:
The answer would be 15 cookies.
Step-by-step explanation:
Cookies = 24 cents each
Pop = 45 cents each
you would need about 2000 pennies to have enough to buy two cookies, 2000-50=1950, so if you have 50 cents you would need 1,950 more pennies to be able to get 2 cookies

Last week, Russell bought 8 pizzas and 10 cakes for a total of $160.
Today, Russell bought 26 pizzas and 8 cakes for a total of $226.
Assuming neither item has changed in price, what is the cost of a pizza in dollars?
Answers
Answer:
$5
Step-by-step explanation:
Create a system of equations where p is the cost of a pizza and c is the cost of a cake
8p + 10c = 160
26p + 8c = 226
Solve by elimination by multiplying the top equation by -4, and the bottom equation by 5
-32p - 40c = -640
130p + 40c = 1130
Add these together:
98p = 490
p = 5
So, the cost of a pizza is $5
solve the equation

A sandbox in the shape of a trapezoid is show below. If a cover is to be made for the sandbox, what if the minimum amount of fabric needed?
Answers
The minimum amount of fabric needed for a sandbox is,
⇒ 72 feet²
We have to given that;
A sandbox in the shape of a trapezoid is show below.
And, a cover is to be made for the sandbox.
Hence,
The minimum amount of fabric needed for a sandbox is,
⇒ Area of fabric = 9 × 7 + (1/2 × 9 × 2)
= 63 + 9
= 72 feet²
Thus, The minimum amount of fabric needed for a sandbox is,
⇒ 72 feet²

Which ratio is smaller, 32 : 24 or 30 : 22?
Answers
Answer:
32 : 24 is smaller
Step-by-step explanation:
32 : 24 = 32/56, reduced is 4/7
30 : 22 = 30/52, reduced is 15/26
a common denominator is 182:
4/7 = 104/182
15/26 = 105/182
You need to get one number from each ratio to be equal
I’m gonna get 32 and 30 to equal
*first divide both ratios by 2(don’t have to do this just makes the no.’s smaller)
32:24
16:12
30:22
15:11
Multiply 16:12 by 15
And multiply 15:11 by 16
32:24 -> 16:12 -> 240:180
30:22 -> 15:11 -> 240:176
176<180
Therefore ratio 30:22 is smaller

Here a = 20,, b= 8
Step-by-step explanation:
Using Pythagoras theorem,
a^2 + 15^2 = 25^2 ,, b^2 + 6^2 =10^2=100
Answer:
a = 20, b = 8
Step-by-step explanation:
Using Pythagoras' identity
The square on the hypotenuse is equal to the sum of the squares on the other 2 sides.
(1)
a² + 15² = 25²
a² + 225 = 625 ( subtract 225 from both sides )
a² = 400 ( take the square root of both sides )
a = [tex]\sqrt{400}[/tex] = 20
(2)
b² + 6² = 10²
b² + 36 = 100 ( subtract 36 from both sides )
b² = 64 ( take the square root of both sides )
b = [tex]\sqrt{64}[/tex] = 8
