"In the diagram, m = 128° and m = 76°. What is mABC?
wel
Angle ABC is an inscribed angle.

Inscribed angle = 1/2 * Intercepted Arc

The intercepted arc is arc CD + arc DA, which would be 128 + 76 = 204

m<ABC = 1/2(204)

m<ABC = 102 degrees

You answer is D) 102

1. The measures of two angels have a sum of 90 degrees. The measures of the angels are in a ratio 2:1 determine the measures of
OLga [1]

Answer:

1) 60 and 30 degrees

2) 150 and 30 degrees

Step-by-step explanation:

(2+1)x=90

3x=90

x=30

2*30=60

1*30=30

The missing angles are 60 and 30 since they are in the 2:1 ratio

(5+1)x=180

6x=180

x=30

5*30=150

1*30=30

The missing angles are 150 and 30 since they are in the 5:1 ratio

Also, it's spelled angles not angels that's different.

Write an equation of the line that passes through (4,−1) and is parallel to the line y=3x+7. (hint: NOT y=3x-13)
CaHeK987 [17]

To find the equation of the line, we are going to use the point-slope form, which is listed below:

(y - y_1) = m(x - x_1)

  • (x_1, y_1) is a point on the line
  • m is the slope of the line

You may notice that we have a point, but no slope is given to us. However, the problem states that the line is parallel to the equation y = 3x + 7, which means that it has the same slope as this line, which is 3. (Remember that this line is set up in y = mx + b form, where m is the slope)


Thus, we can now insert our values into the point-slope formula to find the equation of our line.

(y + 1) = 3(x - 4)

(y + 1) = 3x - 12

y = 3x - 13


The problem made it clear that it didn't want the form y = 3x - 13, so let's put it in standard form:

y = 3x - 13

3x - y = 13


The equation of our line is \boxed{3x - y = 13}.

the area of melanie’s bedroom floor is 1.5 times the area of the kitchen floor. the area of her kitchen floor is k, select each
aliina [53]

For this case we have that the variable "k" represents the floor area of Melanie's kitchen.

We have that the floor area of the room is 1.5 times the floor area of the kitchen, then, we propose the following function to find the floor area of the room:

A (k) = 1.5k\\A (k) = k (1 + 0.5) = k + 0.5k = 1.5k

Answer:

Option A and D
