How far from the door must a ramp begin in order to rise 3 feet with an 8 degree angle of elevation
Answers
Answer:
Step-by-step explanation:
We know that the angle of elevation is 8 degrees.
We know that the height of the opposite side of the angle is 3 feet.
We want to know the adjacent side (the side from the start of the ramp to the bottom of the opposite side)
We can do this with tangent
[tex]tan(8) = \frac{3}{adj} \\adj = \frac{3}{tan(8)} \\adj = 21.34611 feet[/tex]
The distance between the ramp and the door can be calculated using the principle of Pythagoras, Hence, the distance should be 21.34 feets
Angle of elevation = 8°Rise = opposite = 3 feets Distance, d = adjacentUsing SOHCAHTOA :
Tanθ = Opposite / Adjacent
Tan(8°) = 3 / d
0.1405408 = 3 / d
0.1405408d = 3
Divide both sides by 0.1405408 to isolate d
0.1405408d / 0.1405408 = 3 / 0.1405408
d = 21.34 feets
Therefore, the distance of the ramp from the door should be 21.34 feets

Angle a and b are supplementary angles. If m angle a = (x + 15) degrees and m angle b = (x - 13) degrees. Find measure of angle b. Please answer !!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
Answers
Answer:
Step-by-step explanation:
Sum of supplementary angle is 180
So
a+b=180
(X+15)+(X-13)=180
2x+2=180
2x=178
X=178/2
X=89.
So angle b =x-13
=89-13

Your making chocolate chip cookies. The recipe calls for 1/8 teaspoon salt to 1/4 teaspoon baking soda. How much salt is needed for one teaspoon of baking soda
Answers
Answer:
Step-by-step explanation:
this ratio of (1/8) to (1/4) can be written as a fraction
however, since we want to find out how much salt is needed for one teaspoon of baking soda, salt is the numerator (top) of the fraction and baking soda is the denominator (bottom) of the fraction
(1/8)/(1/4)
(1/8)x(4/1) when you divide fractions the second fraction switches the top and bottom
(1/8)x4

1/2
1/2 or 0.5 teaspoons of salt are needed per teaspoon of baking soda

Joe goes to the store to buy milk that cost x + $3, bread that cost x + $2.25, and 3 bags of potato chips that cost x + $1.50 each. Write an equivalent expression to represent what he spent.
Answers
Given:
Milk cost = x + $3,
Bread cost = x + $2.25,
3 bags of potato chips cost = x + $1.50 each.
To find:
The equivalent expression to represent what he spent.
Solution:
1 bag of potato chips cost = x + $1.50
3 bag of potato chips cost = 3(x + $1.50).
Total cost = Milk cost + Bread cost + Cost of 3 bags of potato chips
[tex]\text{Total cost}=(x+\$3)+(x+\$2.25)+3(x+\$1.50)[/tex]
[tex]\text{Total cost}=x+\$3+x+\$2.25+3x+\$4.50[/tex]
[tex]\text{Total cost}=(x+x+3x)+\$(3+2.25+4.50)[/tex]
[tex]\text{Total cost}=5x+\$9.75[/tex]
Therefore, the required expression is 5x+$9.75.

The angles of every triangle add up to 180
Step-by-step explanation:
Angle 2=52) Add 71+57=128. 180-128=52
Angle 1= 123) Angle 57 and 1 are supplementary angles which means they add up to 180. So subtract 57 from 180 which will give you 123.
Angle 3= 29) Now that we know that angle 1 is 123, we add 123 and 28 which gives 151. Then subtract 180-151 which equals 29.
This problem was like a pattern. You work with one part at a time and then you unsolve each part :)

If a||b m<2=63 and m<9=105 find the measure of each missing angle
Answers
Answer/Step-by-step explanation:
Given, m<2 = 63°; m<9 = 105°, and line a is parallel to b:
a. m<1 + m<2 = m<9 (alternate exterior angles are congruent)
m<1 + 63° = 105° (substitution)
Subtract 63 from each side
m<1 = 105° - 63°
m<1 = 42°
b. m<3 + m<2 + m<1 = 180° (angles in a straight line)
m<3 + 63° + 42° = 180° (substitution)
m<3 + 105° = 180°
m<3 = 180° - 105°
m<3 = 75°
c. m<4 = m<1 (vertical angles are congruent)
m<4 = 42°
d. m<5 = m<2 (vertical angles are congruent)
m<5 = 63°
e. m<6 = m<3 (vertical angles are congruent)
m<6 = 75°
f. m<7 = m<9 (vertical angles are congruent)
m<7 = 105°
g. m<8 = m<6 (alternate interior angles are congruent)
m<8 = 75°
h. m<10 = m<8 (vertical angles are congruent)
m<8 = 75°
i. m<11 = m<4 (alternate interior angles)
m<11 = 42°
j. m<12 = 180° - m<11 (linear pair theorem)
m<12 = 180° - 42° (substitution)
m<12 = 138°
k. m<13 = m<11 (vertical angles are congruent)
m<13 = 42° (substitution)
l. m<14 = m<12 (vertical angles are congruent)
m<14 = 138°
