Answer:

∠D B C = 41°

Step-by-step explanation:

Step(i):-

Given ∠ABC = 90°

In diagram ∠D B C + ∠A B D = 90°

6 x+5 + 8 x +1 = 90

14 x + 6 = 90

14 x = 90 -6

14 x = 84

x = 6

Step(ii):-

∠D B C = 6 x + 5 = 6 (6) +5 = 36 +5 = 41

∠D B C = 41°

∠A B D = 8(6) +1 = 49°

∠D B C + ∠A B D = 41° + 49° = 90°

Solve for x and y: x+y=5 x−y=a

9966 [12]

Answer:

x=5/2 + a/2, y= 5/2 - a/2

Step-by-step explanation:

We can solve this system using addition of the equations

x+y=5

x-y=a

2x =(5+a)

x=(5+a)/2= 5/2 +a/2

x=5/2 +a/2

x-y=a

y = x - a , x=5/2 + a/2

y= 5/2 + a/2-a

y= 5/2 - a/2

The volume of a right circular cone is 300 cubic inches. What is the volume, in cubic inches, of

Jet001 [13]

Answer:

900 cubic inches.

Step-by-step explanation:

Given the following data

Volume of right circular cone = 300in³

We know that the volume of a right circular cone is given by the formula;

$V = \frac{1}{3} \pi r^{2}h$

Where;

V is the volume of right circular cone.

r is the radius of the base of the right circular cone.

h is the height of the right circular cone.

The volume of a right circular cylinder is given by the formula;

$V = \pi r^{2}h$

Thus, multiplying the volume of the right circular cone by 3 would give us the volume of the right circular cylinder.

$V = \frac{1}{3} \pi r^{2}h * 3$

Substituting into the equation, we have;

V = 300 * 3

V = 900in³

Therefore, the volume of a right cylinder that has the same base and height as the cone is 900 cubic inches.

Based on this example, make a

Mnenie [13.5K]

Answer:

Step-by-step explanation:

There are 4 of them (acute angles that is)
Those 4 are less than 90 degrees.
They have supplementary angles which are greater than 90 degrees.
There are 4 of them also.
The total number of angles should be 8 if there are 2 parallel lines and 1 transversal.

From what I can see, it might be wanting you to find the distance of the lines connecting the 2 points. Use then distance formula to do that.
