Answer:

The value of x = 30

Step-by-step explanation:

It is given that,

In triangle ABC,

<A = x - 5, <B =  3x + 30 and <C = 35

<u>To find the value of x</u>

<A + <B + <C = 180   [ angle sum property]

(x - 5 ) + (3x + 30 ) + 35 = 180

x - 5 + 3x + 30 + 35 = 180

x + 3x - 5 + 30 + 35 = 180

4x + 60 = 180

4x = 180 - 60

4x = 120

x = 120/4 = 30

Therefore the value of x = 30

<u>To find <A and <B</u>

<A = x - 5

<A = 30 - 5 = 25°

<B =  3x + 30

<B = 3*30 + 30 = 90  + 30 = 120°

Answer:

x=30\ degrees

m

m

Step-by-step explanation:

we know that

The sum of interior angles in a triangle must be equal to 180 degrees

so

(x-5)+(3x+30)+(35)=180\°

solve for x

4x=180\°-60\°

4x=120\°

x=30\°

Constructing Parallel Lines
Orlov [11]

A line is a one-dimensional shape that is straight, has no thickness, and extends in both directions indefinitely. The slope of the lines is -1, and the equation of the parallel line is y-x-6.

<h3>What is the equation of a line?</h3>

A line is a one-dimensional shape that is straight, has no thickness, and extends in both directions indefinitely. The equation of a line is given by,

y =mx + c

where,

x is the coordinate of the x-axis,

y is the coordinate of the y-axis,

m is the slope of the line, and

c is the y-intercept.

The parallel line passes through the points (-4,-2) and (-3,-3). Therefore, the slope of the line is,

Slope = (-2 + 3) / (-4 + 3) = 1/-1 = -1

The equation of the parallel line that is passing through point P is,

y = mx + c

y = -x + c

-3 = -(-3) + c

-3 -3 = c

c = -6

Hence, the slope of the lines is -1, and the equation of the parallel line is y-x-6.

Tomas drew a rectangle with an area of 6 square centimeters. What is the greatest possible perimeter for this rectangle.
Delvig [45]
6 by 1.

This is the greatest because it makes 14 (6+6+1+1), which is greater than 3 by 2, which is only 10. (3+3+2+2)

Hope this helps!

Callies family spends an average of $70 per month electric at that rate what can that family expect to pay electric for 1 year
ivanzaharov [21]

Answer:

$840

Step-by-step explanation:

Callies family spends an average of $70 per month electric. At that rate what can that family expect to pay electric for 1 year

Note that:

1 year = 12 months.

Hence, if:

1 month = $70

12 months = $x

Cross Multiply

$x = 12 × $70

$x = $840

Therefore, the amount that family can expect to pay in 1 year(12 month) for electric = $840

A person bought a water tank of circular base having the radius 1.05 meter and height 3.5 m for the use of own house from the sh
ValentinkaMS [17]

<u>11000 litre of water is needed to fill the tank.</u>

Answer:

solution given:

radius [r]=1.05m

Total height[H]=3.5m

height of cylinder[h]=2.45m

Now

The volume of the cylindrical part of tank=\pi r^2h=3.14*1.05^2 *2.45=8.4815m^3

again

the volume of semi-spherical part of tank=\frac{2}{3} \pi r^{3} =\frac{2}{3}*3.14*1.05^3=2.4233m^3

now

total volume=volume of the cylindrical part of tank + volume of semi-spherical part of tank

=8.4815+2.4233=10.9048 m^{3}

we have

1m^3=1000litre

10.9048m^3=1000*10.9048=10904.8\:litre
