Help Me On Both Of These Qestions Please.

Answers

Answer 1

Answer:

3) m∡ACB = 40 m∡ABC = 63

4) m∡BCA = 14 m∡ABC = 83

Step-by-step explanation:

Since DE is a line it has 180 degrees so:

103 + CAB = 180

CAB = 77 degrees

All triangle interior angles of a triangle add up to 180 degrees, so:

BAC + ACB + CBA = 180

3x - 14 + 3x + 9 + 77 = 180

6x + 72 = 180

6x = 108

x = 18

Plug in your values:

3(18) - 14 = 40

3(18) + 9 = 63

Use the same method for the next problem.

16x^2 + 10x — 27 = -6x + 5

What are the solutions to this equation?

Answers

Answer:

x=1 or x=−2

Step-by-step explanation:

16x2+10x−27=−6x+5

Step 1: Subtract -6x+5 from both sides.

16x2+10x−27−(−6x+5)=−6x+5−(−6x+5)

16x2+16x−32=0

Step 2: Factor left side of equation.

16(x−1)(x+2)=0

Step 3: Set factors equal to 0.

x−1=0 or x+2=0

x=1 or x=−2

What are the steps in solving this system? (write them in WORDS and solve.)

5x - 2y = 4
10x - 2y = 14

Answers

5x - 2y = 4 (1)
10x - 2y = 14 (2)

divide (1) to (2),
-5x = -10
x = 2

Then, to find the y you can substitute the x = 2 to (1),
5(2) - 2y = 4
10 - 2y = 4
- 2y = 4 - 10
- 2y = - 6
y = 3

So, the x = 2 and y = 3

Step-by-step explanation:

Given 2 sides of a triangle then the third side x is in the range

difference of 2 sides < x < sum of 2 sides

(11)

given 2 sides 2, 6 , then

6 - 2 < x < 6 + 2

4 < x < 8

(12)

Given 2 sides 4, 12 , then

12 - 4 < x < 12 + 4

8 < x < 16

(13)

Given 2 sides 2, 11 , then

11 - 2 < x < 11 + 2

9 < x < 13

11 + 22x = 9 + 30x
(Please provide the steps to complete the equation)

Answers

Answer:

x = 4

PLS LOOK AT THE PIC I HAVE SENT YOU, HOPE THIS WILL HELP YOU!

Answer:

x = 1/4

Step-by-step explanation:

11 + 22x = 9 + 30x

subtract 22x from both sides

11 = 9 + 8x

subtract 9 from both sides

2 = 8x

divide both sides by 8

2/8 = x

simplify

1/4 = x

∠A and \angle B∠B are complementary angles. If m\angle A=(2x-10)^{\circ}∠A=(2x−10) ∘ and m\angle B=(x-2)^{\circ}∠B=(x−2) ∘ , then find the measure of \angle A∠A.

Answers

Answer:

118°

Step-by-step explanation:

Two angles are called complementary when their measures add to 90 degrees.

From the question,

Angle A=(2x-10)°

Angle B=(x-2)°

Both Angles are complementary.

Therefore

Step 1

(2x - 10)° + (x - 2)° = 180°

2x + x - 10 - 2 = 180°

3x - 12 = 180°

3x = 180° + 12

3x = 192°

x = 192/3

x = 64°

Step 2

We are to solve for Angle A

(2x-10)°

Angle A = 2(64 ) - 10

Angle A = 128 - 10

Angle A = 118°

The measure of Angle A = 118°
