Answer:
85° and 95°
Step-by-step explanation:
Let's begin noting that a triangle is isosceles if and only if two of its angles are congruent. We can thus find the angle <ABP, recalling that the sum of the interior angles of a triangle is equal to 180°.
[tex] \angle \: ABP = \frac{180 - 80}{2} = 50 \degree[/tex]
Finally, let point K be the intersection between segments BC and PQ, and let's note that the triangle PQB is a right isosceles triangle, since all the angles in a square are equal to 90°, and the two triangles APB and BQC are congruent.
Therefore, the angle BKQ is equal to 180-50-45=85°.
Of course angle BKP=180-85=95°.
Hope this helps :)
The product of (3 - 4i) and ____ is 25.
Answer:
( 3 + 4i )
Step-by-step explanation:
For this problem, we need to know that i^2 = -1. With this, let's solve the multiplication problem.
So to get rid of the i, we know it needs to be squared. The question is, for the sun of the products do we have a -4i or a +4i? So we will test both.
( 3 - 4i )^2 ?= 25
( 3 - 4i )( 3 - 4i ) ?= 25
9 - 12i - 12i - 16 ?= 25
We can stop here since we know that 24i will never equal 25.
So let's try the -4i
( 3 + 4i )( 3 - 4i ) ?= 25
9 + 12i - 12i + 16 ?= 25
9 + 16 ?= 25
25 == 25
Thus, our term for this to be true is ( 3 + 4i ).
Cheers.
This is my last question for an assignment I'm doing. Cannot fathom what I'm supposed to do. Assuming it has to do with Right Triangle Proportions. Any help would be greatly appreciated.
Answer:
x = √7
Step-by-step explanation:
First find the missing angle of the triangle with the side as 5, and the hypotenuse as 6.
a² + b² = c²
5² + b² = 6²
25 + b² = 36
b² = 11
b = √11
So now we know that for the triangle with sides 2 and x, the hypotenuse is √11. Now use the Pythagorean Theorem to find x.
a² + b² = c²
2² + x² = (√11)²
4 + x² = 11
x² = 7
x = √7.

A cone-shaped popcorn cup has a radius of 5 centimeters and a height of 9 centimeters. How many cubic centimeters of popcorn can the cup hold?
Use 3.14 for π (pi).
The volume of the popcorn cup is __ cm^3
Answer:
The cup can hold 235.5 cubic cm of popcorn.
Step-by-step explanation:
A cone shaped popcorn cup has a radius of 5 cm and a height of 9 cm.
Use 3.14 as an approximation for pi.
Now, to find cubic cm of popcorn the cup can hold.
Radius (r)= 5 cm
Height (h)= 9 cm
[tex]\pi[/tex]= 3.14 (as per question).
So, to get the cubic cm of popcorn the cup can hold we put formula of volume:
Volume= [tex]\pi[/tex]r[tex]x^{2}[/tex] h[tex]\frac{x}{y}[/tex] 3
Volume= 3.14 x 5[tex]x^{2}[/tex] × 9[tex]\frac{x}{y}[/tex]3
Volume= 3x14 x 25 x 3
Volume= 235.5 cubic cm.

1. Noah's kite is flying above a field at the end of 65 feet of string. The angle of
elevation to the kite measures 70°. How high is the kite above Noah's head?
a. Identify the trigonometric function you would use to solve.
b. Give the equation you would use to solve.
C. Find the solution to the nearest foot.
Answer:
A) sin θ = opposite/hypotenuse
B) sin 70 = h/65
C) h = 61 ft
Step-by-step explanation:
I have attached an image of the triangle diagram that we will use to since this question.
A) From the image attached, we see that the height of the kite above Noah's head is given by h which is the opposite side of the triangle.
We have the hypotenuse as 65.
Thus, the trigonometric function,we will use is;
sin θ = opposite/hypotenuse
B) From A above, we can plug in the relevant values to get the equation we will use to solve. Thus;
sin 70 = h/65
C) sin 70 = h/65
0.9397 = h/65
h = 65 × 0.9397
h = 61.08 ft
To the nearest foot gives ;
h = 61 ft
I need help with 5 and 6 please what is M and B?
Answer:
Step-by-step explanation:
5)
y= 3x - 5 m = 3 b = -5
y = -x -1 m = -1 b = -1
6)
y= x+3 m = 1 b = 3
y= -2x -3 m = -2 b = -3
Answer:
5.
y = 3x - 5 m = 3 b = -5
y = -x -1 m = -1 b = -1
6.
y = x+3 m = 1 b = 3
y = -2x -3 m = -2 b = -3

how many liter of 30%alcohol solution sholud added to 40 liters o6 60% alcohol solution to prepare 50% solution
Answer:
75
Step-by-step explanation:
75. How many litres of a 30% alcohol solution should be added to 40 litres of a 60% alcohol solution to prepare a 50% solution? \ The ratio in which 30% alcohol and 60% alcohol should be mixed to get 50% alcohol is 1 : 2
Answer: Let x litres of 30% alcohol solution be added.
Then, 30% of x + 60% of 40 = 50% of (x + 40)
⇒ 30x + 60 × 40 = 50 (x + 40)
⇒ 30x + 2400 = 50x + 2000
⇒ 20x = 400
⇒ x = 20

The number of different ways to draw two cards of the same rank will be 1/195.
What is probability?Its fundamental concept is that someone will nearly surely occur. The proportion of positive events in comparison to the total of occurrences.
Then the probability is given as,
P = (Favorable event) / (Total event)
A 60-card deck (assume that there are 4 cards in each rank).
Then the total number of events is given as,
Total event = ⁶⁰C₂
Total event = 60! / [(60 - 2)! x 2!]
Total event = (60 x 59) / 2
Total event = 1,170
The number of the favorable event will be given as,
Favorable event = ⁴C₂
Favorable event = 4! / [(4 - 2)! x 2!]
Favorable event = (4 x 3) / 2
Favorable event = 6
Then the probability is given as,
P = 6 / 1,170
P = 1/195

bricks having volume 500cm^3 each are selected to construct a compound wall of 200m×0.5m×1.5.If theprice of the brick is Rs.14,find the total price.
Answer:
Rs. 4,200,000
Step-by-step explanation:
Given :
Volume of brick = 500cm³
Dimension of wall : 200m×0.5m×1.5m
Converting to cm
Volume of compound wall:
(200 * 100) * (0.5 * 100) * (1.5 * 100)
20000cm * 50cm * 150cm=
= 150000000cm³
Volume of compound wall / volume of brick
1500000000 cm³ / 500 cm³
= 300000
Price per brick = Rs. 14
Total price = 14 * 300000 = Rs. 4,200,000
