Answer:
x= 6°
Step-by-step explanation:
∠DEF +∠EFD= ∠EDG
(ext. ∠= sum of int. opp ∠s)
9x +7° +70°= 21x +5°
21x -9x = 77° -5° (bring x terms to one side)
12x= 72° (simplify)
x= 72° ÷12
x= 6° (simplify)

On her first stroke, Maya hit a golf ball 146 yards, 2 feet, 11 inches. On her second stroke, she hit it 163 yards, 1 foot, 2
inches. How far did the ball go altogether? Convert the answer to larger units whenever possible.
A. 311 yards 11 inches
B. 310 yards, 1 foot, 1 inch
C. 309 yards, 3 feet, 13 inches
D. 309 yards, 1 foot, 1 inch
Answers
Answer:
A
Step-by-step explanation:
1 yard = 36 inches
1 feet = 2 foots = 24 inches
First time, she's got 5315 inches, second time is 5868 inches
5315 + 5868 = 11183 inches
11183 : 36 = 310.638888889 inches
Change it and we have answer A, 311 yards 11 inches

Answers
Answer:
x=2
Step-by-step explanation:
triangle area is 1/2BH
1/2(4x)=4
2x=4
x=2 units
Answer:
Missing side = 2
X= 2
Have given details if x was only base of the side triangle
This is in order to find a completely new triangle with just the height and in order to find and combine 1 given area say if just the right side in your diagram was 4 and we had to find the other triangle. This is only done on scale or 1 given measure or angle for the right side triangle. We was not given this but proved a 0.3 scale.
Area of other triangle =2.66^2
2.66+4 combined = 6.66^2
Step-by-step explanation:
We find a square height is also 4
We also know a right angle triangles height can be found using either 1/2 base or 1/2 height.
So this can mean the height is and stays 4 and the base is 2.
As 1/2 4 height = 2 height
2 unit height x 2 unit base = 4
Therefore, the first triangle slant is the same.
4sq +2sq = c^2
√16+√4 = √20
c^2 = √20 = 4.47 = 4.472135955
c = 4.47 slant
Given a=4 and c=4.47,
b = 1.99522
∠α = 63.49° = 63°29'23"
∠β = 26.51° = 26°30'37"
h = 1.78543
We cna tell now that the triangle is 0.333 smaller so the measurements
Show 2/3 of 2 = 1.333 being the base across
using this as Area we find 1.333 x 2 = 2.666
(1/2 h^b of 4) =2
We can prove with the angles
63 +27 degree or
a^2+b^2 = c^2
1.333^2 + 4^2
= √1.776889+√ 16 = √ 17.776889
c^2 = 4.21626481616
c= 4.22 slant left side (nb right side on attachment)
Angle ∠ A = α = 71.478° = 71°28'39″
Angle ∠ B = β = 63.53° = 63°31'48″
Angle ∠ C = γ = 44.992° = 44°59'33″
We see 63 angle on right lower side of attachment picture in reflection and can prove x = 3.333
But on your diagram base x = 2
What i have done is enlarged x by 0.3 and proven how to find x if x was just one side of the triangle's height.
The triangles even though reflected are identical.
Other info is proven through finding ha and hb heights.
We confirm 4.001 is the hc height of your diagram.
Height: ha = 2.984

Hi, to answer this question we have to apply the next formula:
Volume of a sphere: 4/3 π (diameter /2)^3
Replacing with the values given;
V = 4/3 (3.14) (20/2)^3 = 4/3 (3.14) 10^3 =4,187 in3
The volume of the sphere is 4,187 cubic inches.

Solve the system algebraically. Check your work. 5x + 3y = 18 2x + 3y = 9 Make sure there are NO SPACES in your answer. Be sure to include a comma between the x and y values. ANSWER: {( a0 )}
Answers
Answer:
(3,1)
Step-by-step explanation:
5x + 3y = 18
2x + 3y = 9
So we can use elimination here to solve this system of equations by multiplying the second equation by -1
Now we have:
5x + 3y = 18
-2x - 3y = -9
Now we add straight down and combine like terms
The y terms cancel and we are left with 3x = 9, dividing both side by 3 we get x = 3
Now we can plug this x value into one of the original equations to solve for our y value
I will use the first equation: 5(3) + 3y = 18 → condensing the terms we get 15 + 3y = 18 → subtracting the 15 from both sides we get 3y = 3 → dividing both sides by 3 we get y = 1
The solution to this system of equations is (3, 1)

What is the percentage?The quantity of anything is stated as though it were a fraction of a hundred.
A sample of a mysterious chemical substance naturally gains mass over time.
The relationship between the elapsed time t, in years, since the mass of the sample, M(t), in grams, was initially measured is modeled by the following function:
[tex]\rm M(t) = (1.16)^{4t+3}[/tex]
The yearly percent change in the mass of the sample will be
At t = 0, we have
M(0) = (1.16)³ = 1.561
At t = 1, we have
M(1) = (1.16)⁷ = 2.826
Then the percentage will be
P = [(2.826 – 1.561) / 1.561] x 100
P = 0.8106 x 100
P = 81.06%
