Answer:

Step-by-step explanation:

I assume you are dealing with complementary angles.

m<a + m<b = 90

69 + m<b = 90

m<b = 90 - 69

m<b = 21

Answer:

nice and

since it is complementary then a +b = 90

and substitution gives

69 + b = 90

b = 21

hope this helped and brainliest pls

Subtract the 6 from those taking history and English. Leaves 10.
Subtract the 10 from those taking English.
This leaves 20.
Subtract the 6 from those taking political science and English. Leaves 8.
Subtract 8 from those taking English.
Leaves 12

2. take none of the three courses? 

3. take history, but niether of the other two
Do the same with history as we did with English.

4. take political science and history but not english
16-6 (that take all 3) = 10

Hope at least the partial answer helps!

A rectangle has vertices at these coordinates. (5, −3), (5, −8),(8, −3) What are the coordinates of the fourth vertex of the rec

Katen [24]

Answer:

Coordinate of 4th vertex of the rectangle is ( 8 , -8 ).

Step-by-step explanation:

Given Vertices of Rectangle are ( 5 , -3 ) , ( 5 , -8 ) , ( 8 , -3 )

To find: Coordinate of Fourth Vertex of the rectangle.

First, Plot all given three points on the graph.

Graph is attached.

We know that Opposite sides of the rectangle are equal and parallel.

Also All angles of rectangles are right angle.

So to satisfy these properties of rectangle.

4th coordinate must be on line x = 8 and y = -8.

⇒ Fourth coordinate = ( 8 , -8 )

Therefore, Coordinate of 4th vertex of the rectangle is ( 8 , -8 ).
