Answer:

Step-by-step explanation:

4x+3y=-5 ...(1)

-3x+4y=12 ....(2)

By 3(1)+4(2) gives

12 x+9y-12x+16y=-15+48

25y=33

y=33/25=1.32

from (1)

4x+3(33/25)=-5

4x=-5-99/25=(-125-99)/25=-224/25

x=-224/100=-2.24

Answer:

75°

Step-by-step explanation:

There are 180° in a triangle, so using the ratios and the 180° setup an equation. Solve for x.

5x + 9x + 10x = 180

24x = 180

24x/24 = 180/24

x = 7.5

To find the largest angle measure, use 10x since 10 is bigger than 5 and 9.

10x

10(7.5)

75°
