Answer:

20a. 143 deg

20b. 37 deg

20c. corresponding angles, congruent

20 d. same-side interior angles, supplementary

Step-by-step explanation:

20a.

m<7 = 34

m<5 + m<7 = 180 (linear pair)

m<5 = 180 - 37 = 143

m<4 = m<5 = 143 (alt int angles)

20b.

m<2 = m<7 = 37 (alt ext angles)

20c. corresponding angles, congruent

20d. same-side interior angles, supplementary

(a)

∠7 = 37° = ∠6 ( vertical angles )

∠4 = 180° - 37° = 143° ( 4 and 6 are supplementary interior angles )

(b)

∠2 = 37° (2 and 4 form a straight angle )

(c)

∠4 and ∠8 are corresponding congruent angles

(d)

∠3 and ∠5 are supplementary interior angles

The sum of 2 numbers is 49. The second number is 15 less than the first number. The first number is

liubo4ka [24]

Answer:

x + y = 49

y = x - 15

Step-by-step explanation:

The sum of 2 numbers is 49 means that x+y = 49. (The two numbers are x and y, and the sum of them are 49.)

The second number is 15 less than the first number, means that y = x - 15 (The second number is y, and it is 15 less than x, which is the first number.)

Therefore the equations will be

x + y = 49

y = x - 15

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.
