Hi! i’ll just tell you how to do it: each triangle has to have angles adding to 180. so simply add the other angles together and find the missing one.
According to the question if we take one number as a M and 3 more than other represent m+3
so the equation will be : m+(m+3)=-13
2m+3=-13
2m=-16
m=-8(one number)
to get another number plug in -8 for m and that gives us -8+3=-5
prove if we pluged in all than we get the same result,-8-5=-13
that was the prove of that math hopefully you get it
Answer:
x = 24
Step-by-step explanation:
The 2 triangles are similar hence ratios of corresponding sides are equal, that is
= 3 = 
( multiply by 8 )
x = 8 × 3 = 24
Answer:
(f + g) (x) = 5x - 11
(f - g) (x) = x + 3
Step-by-step explanation:
f(x) = 3x - 7
g(x) = 2x - 4
to find ; (f + g) (x) and (f - g) (x)
now,
(f + g ) (x) = f (x) + g(x)
= (3x - 7) +( 2x - 4 )
= 3x - 7 + 2x - 4
= 5x - 11
again ,
(f - g ) (x) = f(x) - g(x)
= (3x - 7) - (2x - 4)
= 3x - 7 - 2x + 4
= x + 3
