Answer:

Step-by-step explanation:
The sum of triangle angles is 180°
35+45=80
180-80=100
Please solve this pleaseeeeeeeeeee
Answers
Answer:
x = 45
Step-by-step explanation:
x + 2x + x = 180
4x = 180
x = 45
Answer:
Since its a triangle, all the angles must add to 180. So x+x+2x=180. Solve for x and you got your answer.
Step-by-step explanation:
x²+4x+20=0
a=1 b=20 c=4
a=1 b=4 c=-20
a=1 b =4 c = 20
a=1 b=-4 c=0
2x²+6x+5=0
-2x²+x+5 identify the coefficients
Answers
Step-by-step explanation:
The general form of the quadratic equation is :
[tex]ax^2+bx+c[/tex]
The given equation is x²+4x+20=0
On comparing the given equation and the general equation, we find that
a = 1, b = 4 and c = 20
Hence, the correct option is a=1 b =4 c = 20.
If the equation is 2x²+6x+5=0, then
a = 2, b = 6 and c = 5
If the equation is -2x²+x+5
a = -2, b = 1 and c = 5

(5x + 15)⁰+ (3x - 3⁰) = 180⁰ ( same side on interior angle theorm)
(8x + 12)⁰= 180⁰
8x = 168⁰
x = 21
Angle 1 +( 3x - 3)⁰ = 180⁰⁰ ( linear pair)
Angle 1 + 63 - 3⁰ = 180⁰
Angle 1 + 60⁰ = 90⁰
Angle 1 = 180⁰- 60⁰
Angle 1 = 120⁰
Answer:
(5x+15)°+(3x-3)°=180°(by co interior angle)
5x+3x+15 - 3=180°
8x+12=180°
8x=180°-12
8x=168°
x=168/8
x=21
by putting value of x
(3x-3)° = 3×21-3 = 60°
60°+angle 1 = 180°[by linear pair]
angle 1=180°-60°
angle 1=120°

Two cars got an oil change at the same auto shop. The shop charges customers for each quart of oil plus a flat fee for labor. The oil change for one car required 5 quarts of oil and cost $22.15. The oil change for the other car required 7 quarts of oil and cost $25.15. How much is the labor fee and how much is each quart of oil?
Answers
Answer:
Labor = $14.65
Step-by-step explanation:
25.15-22.15= 3 3/2 = 1.5
1qt = $1.5
1.5 x 5 = $7.5
22.15 - 7.5 = $14.65
1.5 x 7 = 10.5
25.15 - 10.5 = $14.65
Labor = $14.65

please fast answer. to find the height of the pole, a surveyor uses a theodolite. the theodolite is 4 ft tall. the surveyor stands 140 feet away from the base of the pole . then she measures the angle of elevation to the top of the pole to be 44. what is the height of the pole? round to the nearest foot.
Answers
Answer:
C. 139 ft
Step-by-step explanation:
Height of the pole = x + 4 ft
First, find x using trigonometric function.
Reference angle = 44°
Opposite side length = x
Adjacent side length = 140 ft
Apply TOA, which is:
Tan 44 = opp/adj
Tan 44 = x/140
Multiply both sides by 140
140 × Tan 44 = x
135.196428 = x
x ≈ 135 ft
✔️Height of the pole = x + 4 ft = 135 + 4 = 139 ft
