19. Find the value of X (In the picture) (giving points to best answer/brainlest)​

Mathematics

Tema [17]3 years ago

Answer:

x = 61 degrees

Step-by-step explanation:

The triangle on the right is isosceles and the base angles are congruent

the sum of the inner angles of a triangle is 180 degrees

2 * 74 + y = 180

148 + y = 180

y = 32 degrees

the total angle is 90 degrees

so we have that

90 - 32 = 58 degrees

Also the left triangle is isosceles, so we have

2x + 58 = 180

2x = 122

x = 61 degrees

4w+15= -13<br><br> -12=n/2-6
Firlakuza [10]

Answer:

For the one including 4w the answer is - 7

The one with n/2 is - 12

Step-by-step explanation:

4w=-13-15

4w=-28

w=-7

Multiply by 2 on both sides

-24=n-12

-24+12=n

Always write it in the variables perspective.

n=-12

Question 8/Multiple Choice Worth 1 points)
Hunter-Best [27]

Answer:

k = 3

Step-by-step explanation:

Given

f(x) = 0.5x

g(x) = 0.5x - k

Required

Find k

<em>The question illustrates changing of positions of lines along the x and/or y axis;</em>

<em>But in this case; if graph f(x) is shifted down, then it represents a negative shift of points in the y axis.</em>

Given that f(x) = 0.5x

and f(x) is shifted down by 3 units to give g(x); then:

f(x) - 3 = g(x)

Substitute 0.5x for f(x)

0.5x - 3 = g(x)

Recall that g(x) = 0.5x - k ---------- (given)

0.5x - 3 = 0.5x - k

Subtract 0.5x from both sides

-0.5x + 0.5x - 3 = -0.5x + 0.5x - k

-3 = -k

Multiply both sides by -1

-3 * -1 = -k * -1

3 = k

k = 3

<em>Hence, the value of k is 3</em>
