Answer:
x = 30
Step-by-step explanation:
Let the measure of ∠MKQ be x°.
It's given that:-
Measure of ∠JKL is twice the measure of ∠MKQ.⇒ ∠JKL = 2∠MKQ
⇒ ∠JKL = 2x° _____ (eqn.1)
∠JKL & ∠MKQ are complementary angles.⇒ ∠JKL + ∠MKQ = 90°
⇒ 2x° + x° = 90°
⇒ 3x° = 90°
⇒ x° = [tex]\frac{90}{3} = 30[/tex]
∴ Hence ,
∠MKQ = 30°∠JKL = 2∠MKQ = 2×30 = 60°Related Questions

48 is 12% of what number?
Answers
Answer:
I'm not sure but from my calculations,it is 400
Answer:
400
Step-by-step explanation:
In order to find out a percentage of something you divide the percent by 100 (12/100) to get a decimal, which would be 0.12. Now with this we already know 12% of something is 48 and in order to find what we took 12% from we divide 48 by 0.12.
48÷0.12 or 48/0.12 = 400

What is the measure of the angle that the ladder makes with the wall?
Answers
Answer:
30°
Step-by-step explanation:
The measure of angle the ladder makes with the wall = 180 - (the measure of angle the ladder makes with the ground + 90°)
Measure of angle the ladder makes with the ground = 180 - 120 = 60°
Therefore,
The measure of angle the ladder makes with the wall = 180 - (60 + 90°)
= 30°

A rectangular paperboard measuring 22 in long and 14 in wide has a semicircle cut out of it, as shown below.
Find the area of the paperboard that remains. Use the value 3.14 for pi, and do not round your answer. Be sure to include the correct unit in your answer.
Answers
Answer:
231.07 in^2
Step-by-step explanation:
The radius of the semicircle is 14/2 = 7 in
22x14 - 3.14x(7^2)/2 = 231.07 in^2
Answer: 231.07 m^2
Step-by-step explanation:
Area of the remaining paperboard = Area of the entire paperboard - Area of semicircle
1. area of paperboard = l*b = 22*14 = 308 m^2
2. area of semi circle = 1/2 pi r^2 = 1/2*3.14*49/2
Therefore, area of remaining paperboard = 231.07 m^2
What value of y makes the equation true?

Answers
Answer:
D) 21
Step-by-step explanation:
y= -7/12× -36
or, y= -7×-3
or, y= 21
Answer:
D
Step-by-step explanation:
Given
[tex]\frac{-7}{12}[/tex] = [tex]\frac{y}{-36}[/tex] ( cross- multiply )
12y = 252 ( divide both sides by 12 )
y = 21 → D

A bonus of £3150 is shared by 15 people who work for a company.
40% of the bonus is shared equally between 3 managers.
The rest of the bonus is shared equally between 12 salespeople.
One of the salespeople says,
“If the bonus is shared equally between all 15 people I will double the money.
Is the salesperson correct?
You must show how you get your answer.
Answers
Answer:
We have a bonus of £3150
40% is divided between 3 managers, so if
100% = £3150
40% = X
Now we can solve this for X by taking the quotient of these two equations:
(100%/40%) = (£3150/X)
Then:
X = £3150*(40%/100%) = £1260
Then each one of the 3 managers gets:
£1260/3 = £420
Each manager gets £420
The other £3150 - £1260 = £1890
are divided between 12 salespeople, then each one gets:
£1890/13 = £157.5
Each one of the salespersons will get £157.5
Now there is the case where we divide the £3150 evenly between the 15 workers.
We get:
£3150/15 = £210
Each worker gets £210.
Notice that before, each salesperson gets £157.5 and in this case, each salesperson gets £210.
Then the statement:
"If the bonus is shared equally between all 15 people I will double the money."
Is false.

The area of a rectangle knitted blanket is 9x^2-6x-8. What are the possible dimensions of the blanket? Use factoring
Answers
Answer:
(3x-4) by (3x+2) or (-3x+4) by (-3x-2)
Step-by-step explanation:
To factor 9x^2-6x-8 we want to find the factors of 9 and the factors of -8 that when multiplied in sequence and then added give us -6.
factors of -8:
-8 & 1
8 & -1
-4 & 2
4 & -2
you might also want to remember that these can be flipped, so if you have -8 & 1 you can also have 1 &-8.
factors of 9:
9 & 1
-9 & -1
3 & 3
-3 & -3
So now we just need to find numbers where
a & b are factors of 9 and c & d are factors of -8 and a*c+b*d=-6,
if that is the case then (ax+c)*(bx+d)=9x^2-6x-8
guess: 3 & 3 and -4 & 2
3*(-4) + 3*2=-12 +6 = -6
so one factoring is (3x-4)*(3x+2)
This means that one of the possible dimensions of the blanket is (3x-4) by (3x+2)
guess: -3 & -3 and 4 & -2
(-3)*4+(-3)*(-2)= -12+6 = -6
so another factoring is (-3x+4)*(-3x-2)
So you could also have a blanket with dimensions (-3x+4) by (-3x-2) but this might not make sense to do because, if you input positive numbers for x you will get negative dimensions which in the real world don't exist for a knitted blanket.
p.s sorry for the late response.

What is the sale price of a bag of potato chips priced 4 and the sale 25% off?
A:$1.50 B:$2 C:$3 D:$2.50
Answers
Answer:
C: $3
Step-by-step explanation:
I think you're saying that the chips cost $4, so that's what I'm going with.
You can think of 25% as 1/4 of the whole. So if you divide 4 by 4, you get 1, so that means that 1/4 of the price is 1.
Now you can subtract 1 from 4 : 4-1= $3
Hope that helps!
$59.75 camera, 4% sales tax
please show in full detail
Answers
Answer:
The total cost would be: $62.14
Step-by-step explanation:
First convert the percent to a decimal, so since it is 4%, you move the decimal two places to the right, so it would be .04.
Next, multiply $59.75 x .04%. This equals $2.39.
Then, take the product and add it to $59.75. So, $59.75 + $2.39.
This equals $62.14!
