Answer:

Option a. 204 degree

Step-by-step explanation:

see the attached figure to better understand the problem

we know that

The semi-inscribed angle is half that of the arc it comprises.

∠B=(1/2)[arc BC]

substitute

78°=(1/2)[arc BC]

arc BC=156°

Remember that

arc BC+arc BCD=360°

arc BCD=360°-156°=204°

Answer:

Step-by-step explanation:

The equation is ax^2 + bx + c = 0.

a = -1, and b = 1.

-1x^2 + 1x + c = 0

-x^2 + x + c = 0

Expand. If necessary, combine like terms. (x+3)(x-3)=

Ne4ueva [31]

Answer:

${x}^{2} - 9$

Step-by-step explanation:

$(x−3)(x+3)$

$x(x+3)−3(x+3)$

$x \times x+x \times 3−3x−3 \times 3$

$x \times x−3 \times 3$

${x}^{2} - 9$

Describe the process

aliina [53]

Answer:

x = 1

y = 10

Step-by-step explanation:

5x + y = 15

Step 1: Move 5x on the other side by subtracting it from both sides

y = 15 - 5x

2x + y = 12

Step 2: Move 2x on the other side by subtracting it from both sides

y = 12 - 2x

Since y = y, that means 15 - 5x = 12 - 2x

Step 3: Add 5x to both sides

15 = 12 + 3x

Step 4: Subtract 12 from both sides

3 = 3x

Step 5: Divide both sides by 3

x = 1

y = 12 - 2x

Step 6: Plug in 1 for x

y = 12 - 2(1)

Step 7: Multiply 2 by 1

y = 12 - 2

Step 8: Subtract 2 from 12

y = 10

What kind of problems need two operations

My name is Ann [436]

Example ig
2x -4= 6
+4. +4
2x. 10

10/2= 5

X=5

This is a two step problem so I hope it’s the same thing. If it’s not I’m sorry
