The complement of the angle is 1/2 of the measure of the angle. Find the measure of the angle.
Group of answer choices
1.180°
2.90°
3.60°
4.30°

Answers

Answer:

choice 2) x = 60°

Step-by-step explanation:

the complement of an angle is an angle that when added to the original angle = 90°

so:

x + 0.5x = 90°

1.5x = 90°

x = 90/1.5 = 60°

Answer:

Answer:

D

Step-by-step explanation:

The vertices of a figure are given. Find the coordinates of the figure after the transformations given. A(−5,3),B(−2,3),C(−2,1),D(−5,1)Reflect in the y-axis. Then dilate with respect to the origin using a scale factor of 2. (help please))!!!

Answers

Answer:

Reflection: A' (5, 3)

                  B' (2, 3)

                  C' (2, 1)

                  D' (5, 1)

Dialation: A"(10, 6)

                B" (4, 6)

                C" (4, 2)

                D" (10, 2)          

Step-by-step explanation:

A(−5,3),B(−2,3),C(−2,1),D(−5,1)

To reflect over the y-axis you change the value of x. In this case all of the values for x are negative. You turn them all into a positive.:

                   A' (5, 3)

                  B' (2, 3)

                  C' (2, 1)

                  D' (5, 1)

To dialate by a scale factor of 2 you multiple everything by 2 and you should get:           A"(10, 6)

               B" (4, 6)

               C" (4, 2)

                D" (10, 2)

I'm trying to solve for X and X+Y. Please help me!

Answers

Answer:

From 12 o'clock position clockwise:

-12

-1

11

12

Step-by-step explanation:

y = -1 (given).

x + y = 11

Plug in -1 for y in the equation (given):

x + (-1) = 11

Isolate the variable, x. Note the equal sign, what you do to one side, you do to the other. Add 1 to both sides of the equation:

x - 1 (+1) = 11 (+1)

x = 11 + 1

x = 12

x + y = ?

x = 12

y = -1

Plug in the corresponding numbers to the corresponding variables:

12 + (-1) = 12 - 1 = 11

xy = ?

x = 12

y = -1

Plug in the corresponding numbers to the corresponding variables. Note that when you multiply a negative and a positive number, your answer will be negative:

12 * -1 = -12

Since Y is -1, X is 12 because 12+-1= 11. Oh and 12•-1 is -12.
