Answer:
1. sin and cos 2. complementary 3. sinA = cosB 4. 80° 5. 17
Step-by-step explanation:
1. cofunctions: having the same value at complementary angles
sin θ = cos (90 - θ), or cos θ = sin(90 - θ)
2. complementary: two angles sum to 90°, supplementary: two angles sum to 180°
one of the angle in a right triangle must be a right angle = 90°
180°(sum of angles of a triangle) - 90° = 90°(the sum of the other two angles) => which is complementary
3. sinA = cosB
4. cos θ = sin(90 - θ)
=> cos 10° = sin(90 - 10°)
=> cos 10° = sin(80°)
5. sin θ = cos (90 - θ)
=> sin 73° = cos (90 - 73°)
=> sin 73° = cos (17°)

Answer:
0 i think
Step-by-step explanation:
Answer:
The answer is -69,420 ! 69,420 - 69,420 = 0. next you multiply it and its 0 again then you add it 69,420 then subtract it equals 0 then subtract again it equals -69,420 then multiply it equals -69,420 then you have to add 69,420 it equals 0 again then you subtracted 69,420 and that means its -69,420!

Is this correct please help
what does t = ??
please help
Answer:
T=116
Step-by-step explanation:
That is a 90 degree angle and a 26 degree angle, so 26+90=116. 360 is the total degrees in all, so 360-116=224. t degrees is 116.
Step-by-step explanation:
t = 90° + 26° { Being vertically opposite angles }
t = 116 °

What is m∠1? Please help
Answer:
∠ 1 = 102°
Step-by-step explanation:
The exterior angle of a triangle is equal to the sum of the 2 opposite interior angles.
∠ 1 is an exterior angle of the triangle , then
∠ 1 = 33° + 69° = 102°
Answer:
102
Step-by-step explanation:
exterior angle rule:
an exterior angle of a triangle is equal to the two opposite interior angles
so m1= sum of opposite interior angles (69 and 33)
69+33=102
so m1 = 102

Find a formula for an arithmetic sequence that begins 80, 83, 86, 89, ...
Answer:
[tex]a_{n}[/tex] = 3n + 77
Step-by-step explanation:
The nth term of an arithmetic sequence is
[tex]a_{n}[/tex] = a₁ + (n - 1)d
where a₁ is the first term and d the common difference
Here a₁ = 80 and d = a₂ - a₁ = 83 - 80 = 3 , then
[tex]a_{n}[/tex] = 80 + 3(n - 1) = 80 + 3n - 3 = 3n + 77

Yesterday only 13 students were absent. The is 4% of the schools enrollment. What is the schools total enrollment?
Answer: 325 students
Step-by-step explanation:
13 students were absent and this is 4% of the school's total enrollment.
If 13 students represent 4% of the students, assume that x represents 100% of the students:
4% * x = 13
0.04x = 13
x = 13/0.04
x = 325 students
There are 325 students in this school.
what is this area? marking brainliest
Answer:
57in^2
Step-by-step explanation:
Divide the shape into 2 recatngles.
Imagine a line cuts away a rectangle of length 12in by width 4in. from a square of length (12-9)in. and width (7-4)in
This gives you 2 different shapes
Find their area
Rectangle one has an area of = 12in x 4in = 48in^2
Square has an area of = (12-9) in x (7-4) in = 3x 3 inch = 9in.^2
Find their sum to find the area of the whole compound shape:
48+9 = 57in^2

30/(5+7)
parenthesis first so
5+7 = 12
30/12
then division
30/12= 2 6/12
6/12 can be simplified by 6 so
6/6 = 1 and 12/6 = 2
So your answer would be 2 1/2

Answer:
x = 11
Step-by-step explanation:
Assuming that segment EG is a diameter we can solve this using the straight angle theorem ( Which states that angles on a straight line add up to equal 180. Also note that central angles and there corresponding arcs are congruent. )
We are also told that CH is a bisector.
A bisector splits an angle into TWO EQUAL parts.
mDG is split into mDC and mCG
So mDC = mCG
This meaning that because mDC = 7x + -1 , mCG also equals 7x - 1
Leading to us having enough information to use the straight line theorem ( which also works with half circles and arcs. )
So 180 = 2 ( 7x - 1 ) + 2x + 6
now we solve for x
step 1 distribute the 2
2 * 7x = 14x
2 * - 1 = -2
now we have 180 = 14x - 2+ 2x + 6
step 2 combine like terms
14x + 2x = 16x
-2 + 6 = 4
now we have 180 = 16x + 4
step 3 subtract 4 from each side
4 - 4 cancels out
180 - 4 = 176
Now we have 176 = 14x
step 4 divide each side by 14
176 / 16 = 11
14x/14 = x
we're left with x = 11
x-y=4

A candle burns down at the rate of 0.75 inches per hour. The original height of the candle was 9 inches.
Part A: Write a list of 6 ordered pairs to show the height of the candle in inches (y) as a function of time in hours (x) from the first hour after it started burning. For example, the point (0, 9) would represent a height of 9 inches after 0 hours. Explain how you obtained the ordered pairs. (5 points)
Part B: Is this relation a function? Justify your answer using the list of ordered pairs you created in Part A. (2 points)

How many flowers, spaced every 3 in., are needed to surround a circular garden with a 125 -ft radius? Use 3.14 for (the pie symbol).
Answer:
785
Step-by-step explanation:
flowers needed to surround the garden = circumference of the garden / space
circumference of a circle = 2nr
n = 3.14
r = radius
The radius is in ft and the space is in inches. i would convert the ft to inches to aid comparability
1ft = 12 inches
125 x 3 = 375
2 x 3.14 x 375 = 2355
flowers needed = 2355 / 3 = 785
