Answer:

(C)

Step-by-step explanation:

Given: The ΔABC.

To prove: the sum of interior angles measures of ΔABC is 180°.

Proof:

Statement                                                            Reason

1. Let points A, B and C form a triangle             given

2. Let DE be a line passing       Defining a parallel line and labeling angles

through B and parallel to AC

with angles as labelled.

3. ∠1≅∠4 and ∠3≅∠5                Alternate interior angles theorem

4. m∠1=m∠4 and m∠3=m∠5    Congruent angles have equal measures

5.m∠4+m∠2+m∠5=180°         Angle addition and definition of straight line

6.m∠1+m∠2+m∠3=180°            Substitution

Hence proved

hence, option C is correct

What are the x- and y-intercepts of the graph of 3x - 4y = 9?​
coldgirl [10]

Answer:

The X and Y intercepts and the Slope are called the line properties. We shall now graph the line -3x-4y-9 = 0 and calculate its properties. Graph of a Straight Line : Calculate the Y-Intercept : Notice that when x = 0 the value of y is 9/-4 so this line "cuts" the y axis at y=-2.25000. y-intercept = 9/-4 = -2.25000.

Step-by-step explanation:

Find the X and Y Intercepts 3x-4y=9. 3x − 4y = 9 3 x - 4 y = 9. Find the x-intercepts. Tap for more steps... To find the x-intercept (s), substitute in 0 0 for y y and solve for x x. 3 x − 4 ⋅ 0 = 9 3 x - 4 ⋅ 0 = 9. Solve the equation. Tap for more steps... Simplify 3 x − 4 ⋅ 0 3 x - 4 ⋅ 0.

А)
Nookie1986 [14]

Answer:

Step-by-step explanation:

surface area of sphere=a

4pir^2=a

r^2=a/4p

r=root(a/4pi)

if radius is doubled

r1=2root(a/4pi)

r1^2=4(a/4pi)

a/a1=(4pia/4pi)/(4pi 4a/4pi)=1/4

so a is increased by 4 times
