Answer:
-2.31
Step-by-step explanation:
9/7 multiplied by (-9/5) is -2.31.
You first have to change the denominator into a common factor that each fraction has in common.
Then you just multiply them to get -2.31.
When you add up all the angles, it would be equal to 180 degrees.
Since angles 2 and 3 are congruent, angle 3 is also equal to 6x + 24.
We know also that angles 3 and 4 are complementary, so (6x+24) + 5x = 90.
Let's find x.
6x+24+5x = 90
11x = 90-24
11x = 66
x = 6
Angle 2 and 3 are 6(6) + 24 = 60 degrees
Angle 4 is 5(6) = 30 degrees
180 - 60 - 60 - 30 = 30 degrees
Angle 1 is equal to 30 degrees :D :D
