Answer:
PQ=6,69 units
Step-by-step explanation:
b/Sin32°=c/Sin72°
PQ/Sin32°=12/Sin72°
PQSin72°=12Sin32°
PQ=12Sin32°/Sin72°
PQ=6.69 units
By the concept of the sine rule of triangles the value of PQ is 6.6 units.
What is a triangle?A triangle is a three-sided closed-plane figure formed by joining three noncolinear points. Based on the side property triangles are of three types they are Equilateral triangle, Scalene triangle, and Isosceles triangle.
We know the sine rule of a triangle states a/sinA = b/sinB = c/sinC.
Given, In a triangle PQR, Q= 72 degrees, R = 32 degrees, and PR= 12.
Let, q is the opposite side to ∠Q and r is the opposite side to ∠R.
Therefore,
q/sinQ = r/sinR.
12/sin72 = r/sin32.
12/0.951 = PQ/0.523.
PQ = (12×0.523)/0.951.
PQ = 6.6

Given the Trapezoid ABCD
Find the length of AD
Answer:
AD = 230
Step-by-step explanation:
here, we want to find the measure it AD
To do this, we need the value of x firstly
To get this, we are going to use the trapezoid midpoint theorem
The theorem is that the sum of the two parallel sides of a trapezoid when divided by 2 will give the middle point length of the trapezoid
Applying this:
1/2{30x-10+ 30x + 28} = 31x + 1
2(31x + 1) = 60x+ 18
divide both sides by 2
31x + 1 = 30x + 9
31x -30x = 9-1
x = 8
But;
AD = 30x-10
AD = 30(8)-10
AD = 240-10
AD = 230

Step-by-step explanation:
An air-conditioning company counted 56 invoices at the end of the month. They charge $450 for a new installation and $75
for a service call. The total dollar amount of the invoices was $9,450.
How many installations and service calls did the company perform?
Answer:
14 installatons
42 service calls
Step-by-step explanation:
Let x = no. of new installations
y = no. of service calls
(1) x + y = 56 (2) 450x + 75y = 9450
y = 56 - x 450x + 75(56 - x) = 9450
450x + 4200 - 75x = 9450
375x = 5250
x = 14 installatons
y = 56 - 14 = 42 service calls
The number of installations are 14 and number of service calls are 42
What is Equation?Two or more expressions with an Equal sign is called as Equation.
Given,
An air-conditioning company counted 56 invoices at the end of the month.
For installation it charges $450 and $75 for a service call.
Let x be number of installations
y be number of service calls
x+y=56...(1)
and 450x+75y=9450..(2)
From equation 1
x=56-y
Now substitute x value in equation 2
450(56-y)+75y=9450
Apply distributive property
25200-450y+75y=9450
25200-375y=9450
Subtract 25200 from both sides
-375y=9450-25200
-375y=-15750
Divide both sides by 375
y=42
Now put y value in equation 1
x+42=56
x=14
Hence, the number of installations are 14 and number of service calls are 42

Answer:
x = 16.64
option A
Step-by-step explanation:
Using the pythagoreom therom
Answer:
16.64
Step-by-step explanation:
Since it's a right angled triangle, we use Pythagoras theorem:
(Hypotenuse)² = (base)² + (perpendicular)²
x² = 14² + 9²
x² = 196 + 81
x² = 277
√x² = √277
x = 16.64

Answer:
x=-4/3, y=3/-5
Step-by-step explanation:
X+2X=-4
Then, adding up we get: 3x=-4
Then, x=-4/3
Substituting those we get: 3*(-4/3)-5y=-1
-4-5y=-1
-5y=-1+4=3
y=3/-5
Thus, x=-4/3, y=3/-5
