Answer:

x = 31 degrees

Step-by-step explanation:

First things first, all angles of a triangle add up to 180 degrees.

From here, we can put it into an equation:

2x + 3 + x + 1 + 3x - 10 = 180

Simplify

6x - 6 = 180

+ 6 + 6

6x = 186

Divide

x = 31

Hope this helps :)

Answer:

H is the Answer

Step-by-step explanation:

Apply distance formula.

$(x {}^{2 } - {x}^{1} ) {}^{2} + ( {y}^{2} - {y}^{1} ) {}^{2} = d {}^{2}$

where d is the distance.

$( - 5 - 7) {}^{2} + (0 - 5) {}^{2} =$

$- 12 {}^{2} + - 5 {}^{2} = {d}^{2}$

$\sqrt{169} = {d}^{2}$

$d = 13$

Andrej [43]

FOUND THE COMPLETE QUESTION IN ANOTHER SOURCE.ATTACHED IMAGE.
For this case what we have is the following:
For the two semicircles we can model it as a complete circle.
We have to then:

Perimeter:
P = 2 * pi * r
or
P = pi * d
Where,
r = radius
d = diameter
Therefore the perimeter is:
P = 10 * pi
For the largest circle we have:
radius = 10
Perimeter:
P '= 2pi10
P '= 20pi
1/4 since 1/4 circle:
P '' = 20pi / 4 = 5pi
Then, the total perimeter of the source is:
Pt = P + P '' = 10pi + 5pi = 15pi
Pt = 15 * (3.141592)
Pt = 47.1239
round
Pt = 47.1 ft

Area:
The total area will be:
A = A (two semicircles) + A (quarter big circle)
A = (pi / 4) * (d ^ 2) + (1/4) * pi * r ^ 2
A = (pi / 4) * ((10) ^ 2) + (1/4) * pi * (5) ^ 2
A = 98.17477042 feet ^ 2
Round:
A = 98.2 feet ^ 2

Answer:
Perimeter of the source:
Pt = 47.1 ft
Area of the source:
A = 98.2 feet ^ 2
