Find the value of x.
Answer:
Value of x is 92°.
Step-by-step explanation:
The given figure is a cyclic quadrilateral. All the sides of the quadrilateral touches the circle. So, the sum of the opposite angles will always be 180°.
88° + x° = 180°
x° = 180° - 88°
x = 92°.Please HELP QUICK!!!!!!!
Answer:
60.16 mStep-by-step explanation:
Trigonomos used tangent to solve it.
Let the width of the river is w.
tangent = opposite leg / adjacent legtan 76° = w / 15w = 15 tan 76°w = 60.16 mLet that be x
tanØ=Perpendicular/Basetan76=x/15x=15tan76x=60.16mWhat is the equation of the line that passes through the point (1, 3) and is perpendicular to the line 2x+3y=15?
Answer:
y=2x+1
Step-by-step explanation:--------------------------------------------------------------------------------------------------------------
Rearrange 2x+3y=15 by subtracting 2x by both sides. Dividing 3y by both sides.
1⇒[tex]2x-2x+3y=15-2x[/tex]
2⇒[tex]\frac{3y=15-2x}{3y}[/tex]
[tex]y=5-\frac{2}{3} x[/tex]
We know this slope is negative. Meaning for the perpendicular crossing to work, it must have a positive slope. We know that 3=(1*M)+B. Perpendicular lines will have slopes that are negative reciprocals of one another.
--------------------------------------------------------------------------------------------------------------
We know the slope must be between 1 and 3. We know the base must be between 1 and 3.
Using the slope formula y-y/x-x

The mathematical sentence that expresses the information is t + 8 > 82
What is Inequality?A relationship between two expressions or values that are not equal to each other is called 'inequality.
The current temperature is represented by t.
If the temperature rises by 8 degrees, then the new temperature would be t + 8.
The record-high temperature for that date is 82 degrees.
If t + 8 is greater than 82, then the temperature would break the record-high temperature for that date.
Therefore, the mathematical sentence that expresses the information above is t + 8 > 82

Which is larger? The measure of a central angle of a circle that intercepts a 68 degree arc of the measure of an inscribed angle of a circle that intercepts a 68 degree arc. Explain
Answer:
The measure of a central angle of a circle that intercepts a 68° arc
Step-by-step explanation:
Recall the inscribed angle theorems:
Measure of central angle = measure of intercepted arc
Measure of inscribed angle = ½(measure of intercepted arc)
Therefore,
The measure of a central angle that intercepts a 68° arc = 68°
Measure of an inscribed angle of a circle that intercepts a 68° arc = ½(68°) = 34°
Therefore, the larger would be:
The measure of a central angle of a circle that intercepts a 68° arc

Consider the graph y = 2x2 + 7x + 6.
a) The graph of this equation is called a parabola. Does this parabola open
upward or downward? How do you know?
b) What is the y-intercept? How do you know?
c) Find the x-intercepts. Show relevant process.
Answer:
a) Parabola opens up
b) 6
c) -3/2 and -2
Step-by-step explanation:
a) The general form of a parabolic graph is;
y = ax^2 + bx + c
if a is positive, it faces up, if negative, it opens down
Since a = 2 here, it is positive and thus the parabola faces or opens up
b) The y-intercept is simply the c term
the value here is 6
The y intercept is obtained when the x value is zero
So by simply setting the x value to zero, we can easily get the y value since x is zero at that point
c) The x-intercepts refer to the roots of the equation
By solving the quadratic equation i.e substituting 0 for y, we can get the two x values as follows;
2x^2 + 7x + 6 = 0
2x^2 + 4x + 3x + 6 = 0
2x(x + 2) + 3(x + 2) = 0
(2x + 3)(x + 2) = 0
2x + 3 = 0 or x + 2 = 0
2x = -3 or x = -2
x = -3/2 or x = -2

2. FGH ~ TUV. Angle F measures 90°, angle G measures 30°,
and angle H measures 60°. What is the measure of angle U?
I will give Brainliest stars and thx to the first right answer
Answer:
<U = 30
Step-by-step explanation:
Since the triangles are similar
<F = <T
<G = <U
< H = <V
We are told that <G = 30 so < U = 30
Answer:
30°
Step-by-step explanation:
∠G corresponds to ∠U
if ∠G is 30° then so is ∠U
A line passes through the point (-9,5) and has a slope of
4/3
Write an equation in point-slope form for this line.
Answer:
y=4x/3+17
Step-by-step explanation:
4/3=y-5/x+9
y=4x/3+17
The equation in point-slope form for this line is -
(y - 5) = (4/3)(x + 9)
What is the general equation of a Straight line?
The general equation of a straight line is -
y = mx + c
where -
[m] → is slope of line which tells the unit rate of change of [y] with respect to [x].
[c] → is the y - intercept i.e. the point where the graph cuts the [y] axis.
Other possible equations of lines are -
(y - y₁) = m(x - x₁) {Point - slope form}(y - y₁) = (y₂ - y₁) × (x - x₁)/(x₂ - x₁) {Two point - slope form}x/a + y/b = 1 {intercept form}x cos(β) + y sin(β) = L {Normal form}We have a line that passes through the point (-9,5) and has a slope of
4/3.
The point slope form is given by -
(y - y₁) = m(x - x₁)
Now, we can write the equation as -
(y - 5) = (4/3)(x + 9)
Therefore, the equation in point-slope form for this line is -
(y - 5) = (4/3)(x + 9)

which equation has an a-value of 1 ,a b- value of -3 and a c value of -5
Answer:
The options are not given, so I will answer in a general way:
A quadratic equation can be written, in general form, as:
y = a*x^2 + b*x + c
Then if we want this, we need to replace:
a = 1
b = -3
c = -5
Then the equation that we want is:
y = x^2 - 3*x - 5
Is likely that the options are in the factorized way to write a quadratic equation (so it is kinda harder to you)
Such that the factorized way is written as:
y = (x - k)*(x - h)
where k and h are the roots of the quadratic equation.
So you just need to expand that expression and find the one that looks like:
y = x^2 - 3*x - 5
Just to be complete, let's find the factorized form of this particular quadratic equation.
The roots are given by:
0 = x^2 - 3*x - 5
And the two solutions are given by Bhaskara's formula:
[tex]x = \frac{-(-3) \pm \sqrt{(-3)^2 - 4*1*(-5)} }{2*1} = \frac{3 \pm 5.39}{2}[/tex]
The two roots are:
h = (3 + 5.39)/2 = 4.195
k = (3 - 5.39)/2 = -1.195
Then the factorized form is:
y = (x - 4.195)*(x + 1.195)

find the value of X and Y triangle BLT is congruent to Triangle JFK
Using the order of the letters in the triangles find the corresponding sides:
BL is similar to JF
LT is similar to KF
BT is similar to JK
Find the scale between LT and KF
9/12 = 3/4
The smaller triangle is 3/4 the size of the lager one.
This means BT = 3/4(JK) = 3/4(4) = 3
So x = 3, so side BL = 2x = 2(3) = 6
Now to solve for y:
BL is 3/4(JF)
6 = 3/4(y)
Solve for y by dividing both sides by 3/4
Y = 6/(3/4)
Y = 8
X = 3, y = 8
