As per diagram we have:
∠ECA ≅ ∠DCB - vertical anglesm∠ECA + m∠ABC = 180° - supplementary anglesm∠ECA = 3x + 5m∠ABC = x + 11Substitute values and solve for x:
3x + 5 + x + 11 = 1804x = 164x = 41Find the required angle measure:
m∠DCB = 3*41° + 5° = 128°Answer:
m∠DCB = 3*41° + 5° = 128°

30% of 50
what’s the easiest and fastest way to solve it?
Answers
Step 2: We represent the unknown value with $x$.
Step 3: From step 1 above,$50=100\%$.
Step 4: Similarly, $x=30\%$.
Step 5: This results in a pair of simple equations:
$50=100\%(1)$.
$x=30\%(2)$.
Step 6: By dividing equation 1 by equation 2 and noting that both the RHS (right hand side) of both
equations have the same unit (%); we have
$\frac{50}{x}=\frac{100\%}{30\%}$
Step 7: Again, the reciprocal of both sides gives
$\frac{x}{50}=\frac{30}{100}$
$\Rightarrow x=15$
Therefore, $30\%$ of $50$ is $15$
Answer:
15
Step-by-step explanation:
change the percent to a decimal
30% to .30

Albert O'Malley signs a promissory note for $3,500 for 150 days at 9% exact interest. Find the interest he must pay _____ and the total amount due on the due date _____.
Answers
Answer:
He must pay $129.45 and the total amount due is $3,629.45.
Step-by-step explanation:
I (interest) =P (principal) x R (rate) x T (time)
I=3500x.09x150/365
I=129.45
A (amount due) = P (principal) + I (interest)
A= 3500 + 129.45
A= $3629.45

Evaluate the expression 6 + 4 x {3+7}.
Answers
Answer:
46
Step-by-step explanation:
6 + 4 x {3+7} [B.O.D.M.A.S rule] (First bracket)
= 6 + 4 × 10. (Then Multiplication)
= 6 + 40. ( At last addition)
= 46 (Ans)
The simplified value of the expression 6 + 4 × {3 + 7} is 100.
What is PEMDAS rule?PEMDAS rule states the correct order of simplifying an expression is as follows -: Parenthesis, exponents, multiplications, divisions, additions, and, subtractions.
Given, An expression 6 + 4 × {3 + 7}.
First, we'll add 6 and 4 as 3 and 7 are inside curly brackets,
not in parentheses.
Therefore,
6 + 4 × {3 + 7}.
= 10 × {3 + 7}.
Now, we can either distribute the terms or take the addition and multiply.
= 10 × 10.
= 100.

What are trigonometric relations?
Trigonometry is the study of the relationships between the angles and the lengths of the sides of triangles
The six trigonometric functions are sin , cos , tan , cosec , sec and cot
Let the angle be θ , such that
sin θ = opposite / hypotenuse
cos θ = adjacent / hypotenuse
tan θ = opposite / adjacent
tan θ = sin θ / cos θ
cosec θ = 1/sin θ
sec θ = 1/cos θ
cot θ = 1/tan θ
Given data ,
Let the triangle be ΔPQR
Let the angle ∠P = θ
Triangle ΔPQR is a right angle triangle
where ∠Q = 90°
Now , the value of the sides are
PQ = 8 cm
QR = 15 cm
PR = 17 cm
Now , from the trigonometric relations
∠QPR = θ
tan θ = opposite side / adjacent side
Opposite side of Triangle PQR is QR
Adjacent side of Triangle PQR is PQ
So , substituting the values in the equation , we get
tan θ = opposite side / adjacent side
tan θ = QR / PQ
tan θ = 15 / 8
tan θ = 1.875
Now , the value of θ is
The value of θ = tan⁻¹ ( 1.875 )
The value of θ = 61.93°
Therefore , the value of θ is 61.93°
Hence , The value of angle P of the triangle ΔPQR is ∠P = 61.93°

Find the y intercept of the following line (-2,1) and (1, 2.5)
Answers
Answer:
2
Step-by-step explanation:
(-2 , 1) ; (1, 2.5)
Slope = [tex]\frac{y_{2}-y_{1}}{x_{2}-x_{1}}\\[/tex]
[tex]\frac{2.5-1}{1-[-2]}\\\\= \frac{1.5}{1+2}\\\\=\frac{1.5}{3}\\\\= 0.5[/tex]
m =0.5
y -y1 =m(x -x1)
y - 1 = 0.5(x - [-2])
y - 1 = 0.5(x + 2)
y -1 = 0.5x + 0.5*2
y - 1 =0.5x + 1
y = 0.5x + 1 + 1
y = 0.5x + 2
y-intercept = 2

Answers
Answer: 112, 68, 22, 90
Step-by-step explanation:
This is fairly somewhat easy
since the adjacent side of 1 is 68 degrees
then 1 would be 112 degrees to make it supplementary to 180 degrees
angle 3 is vertical of angle 68
making it 68 degrees
angle 5 is given to be 90 degrees meaning angle 4 is inbetween
angles 3 and 5 so ( 68 and 90 ) that'll add up to 158 meaning angle 4
is 22
angle 1 = 112
angle 3 = 68
angle 4 = 22
angle 5 = 90

area of the square is triple the area of the rectangle. Find the dimensions of
each figure.

4x = 3(x+6)
4x=3x+18
