Inverse Trigonometry solve the questions below
Answer:
1. θ = 34.85°
2. x = 36.31°
3. x = 39.80°
Step-by-step explanation:
1. Determination of θ.
Adjacent = 11.9
Hypothenus = 14.5
Angle θ =?
Cos θ = Adjacent /Hypothenus
Cos θ = 11.9 / 14.5
Cos θ = 0.8207
Take the inverse of Cos
θ = Cos¯¹ 0.8207
θ = 34.85°
2. Determination of x
Opposite = 9 m
Hypothenus = 15.2 m
Angle x =?
Sine x = Opposite /Hypothenus
Sine x = 9 / 15.2
Sine x = 0.5921
Take the inverse of Sine
x = Sine¯¹ 0.5921
x = 36.31°
3. Determination of x
Opposite = 10 in
Adjacent = 12 in
Angle x =?
Tan x = Opposite / Adjacent
Tan x = 10 / 12
Tan x = 0.8333
Take the inverse of Tan
x = Tan¯¹ 0.8333
x = 39.80°

3/4 divided by 1/2 brainleist if answer
Answer:
1 2/4 (1 1/2)
Step-by-step explanation:
keep, change, flip is how you solve these kinds of problems
the 3/4 stays the same
you turn the ÷ into x
and flip the 1/2 (2/1)
so it becomes
3/4x2/1= 1 2/4 (simplified is 1 1/2)
for the Indicated variable.

A broker charges customers a fixed fee of 150 plus 5.50% of the amount of all investments made. If a customer invests £40000 through the broker what is the total brokerage payable.
Answer:
£2350
Step-by-step explanation:
Commission on the £40,000 = 0.055 x £40000 = £2,200
Total brokerage payable = £2,200 + £150 = £2350

Step-by-step explanation:
t1 = d1/v1 , t2 = d2/v2.
d1 = d2 , and v1 = 0.8 v2
t1 / t2 = d1/d2 x v2/v1 = v2/v1 ( as d1 = d2 )
t1/t2 = v2 / v1 = v2/0.8 v2 = 1/0.8 = 1.25
Need help don’t know what to do I’m confused
Answer:
last option; h = 2t - d
Step-by-step explanation:
t = 1/2(d + h)
t = [tex]\frac{d}{2}[/tex] + [tex]\frac{h}{2}[/tex]
now multiply each side by 2 to eliminate denominator
2t = 2 ([tex]\frac{d}{2}[/tex] + [tex]\frac{h}{2}[/tex])
2t = d + h
h = 2t - d

Answer:
y = 30200
x = -29950
Step-by-step explanation:
1.)
Let x represent children and y for adults.
200x + 450y = 7,600,000
x + y = 250
2.)
200x + 450y = 7,600,000
x + y = 250
-200(x + y = 250)
-200x + -200 = -50000
200x + 450y = 7,600,000
+ -200x + -200 = -50000
——————————————-
250y = 7550000
y = 30200
x + 30200 = 250
x = -29950
Uhm so I don’t know why for children I got a negative number? The wording for this question is very weird.

write the equation for the line in slope-intercept form (2,-3) (-1/2) ( HELP PLEASE )
Answer:
A linear equation is a fancy term for a straight line, which can be created by joining 2 points.
A point can be defined by (x, y), where x and y are the horizontal distance and the vertical distance respectively from point (0,0) (called the origin).
There are 3 ways to define a line:
(1) The slope-intercept form
y = mx + b, in which m is the slope, b is the y-intercept, where the line crosses the vertical axis at (0, b). If values of m and b are given, you can substitute and write the equation right away.
The slope, m, is calculated by rise (vertical difference between 2 points on the line) divided by run (horizontal difference between the 2 points on the line)
Step-by-step explanation:
or example, if 2 points on the line are
(x1, y1) and (x2, y2)
Then slope = (y1– y2)/(x1 — x2)
If m > 0, then the line rises to the right.
If m = 0, then the line is horizontal.
If m < 0, then the line rises to the left.
If the line is in the form x = c, where c is a constant, then the line is vertical.
(2) Point slope form
m = (y — y1)/(x — x1), when (x1, y1) and m are given.
In other words,
m(x — x1) = y — y1
mx — m(x1) = y — y1
y = mx — m(x1) + (y1)
Note that b = -m(x1) + (y1)
(3) linear form
ax + by + c = 0, where a, b, and c are constants.
